* functionalities of the 7 analog comparators (COMP1, COMP2...COMP7) peripheral:
* + Comparators configuration
* + Window mode control
*
@verbatim
==============================================================================
##### COMP Peripheral features #####
==============================================================================
[..]
The device integrates 7 analog comparators COMP1, COMP2...COMP7:
(#) The non inverting input and inverting input can be set to GPIO pins
as shown in table1. COMP Inputs below.
(#) The COMP output is internally is available using COMP_GetOutputLevel()
and can be set on GPIO pins. Refer to table 2. COMP Outputs below.
(#) The COMP output can be redirected to embedded timers (TIM1, TIM2, TIM3...)
Refer to table 3. COMP Outputs redirection to embedded timers below.
(#) The comparators COMP1 and COMP2, COMP3 and COMP4, COMP5 and COMP6 can be combined in window
mode and only COMP1, COMP3 and COMP5 non inverting input can be used as non-inverting input.
(#) The seven comparators have interrupt capability with wake-up
from Sleep and Stop modes (through the EXTI controller):
(++) COMP1 is internally connected to EXTI Line 21
(++) COMP2 is internally connected to EXTI Line 22
(++) COMP3 is internally connected to EXTI Line 29
(++) COMP4 is internally connected to EXTI Line 30
(++) COMP5 is internally connected to EXTI Line 31
(++) COMP6 is internally connected to EXTI Line 32
(++) COMP7 is internally connected to EXTI Line 33

##### How to use this driver #####
==============================================================================
[..]
This driver provides functions to configure and program the Comparators
of all STM32F30x devices.
To use the comparator, perform the following steps:
(#) Enable the SYSCFG APB clock to get write access to comparator
register using RCC_APB2PeriphClockCmd(RCC_APB2Periph_SYSCFG, ENABLE);
(#) Configure the comparator input in analog mode using GPIO_Init()
(#) Configure the comparator output in alternate function mode
using GPIO_Init() and use GPIO_PinAFConfig() function to map the
comparator output to the GPIO pin
(#) Configure the comparator using COMP_Init() function:
(++) Select the inverting input
(++) Select the non-inverting input
(++) Select the output polarity
(++) Select the output redirection
(++) Select the hysteresis level
(++) Select the power mode
(#) Enable the comparator using COMP_Cmd() function
(#) If required enable the COMP interrupt by configuring and enabling
EXTI line in Interrupt mode and selecting the desired sensitivity
level using EXTI_Init() function. After that enable the comparator
interrupt vector using NVIC_Init() function.

* @brief This file provides firmware functions to manage the following
* functionalities of the Digital-to-Analog Converter (DAC) peripheral:
* + DAC channels configuration: trigger, output buffer, data format
* + DMA management
* + Interrupts and flags management
*
@verbatim
===============================================================================
##### DAC Peripheral features #####
===============================================================================
[..] The device integrates two 12-bit Digital Analog Converters that can
be used independently or simultaneously (dual mode):
(#) DAC channel1 with DAC_OUT1 as output
(#) DAC channel2 with DAC_OUT2 as output
[..] Digital to Analog conversion can be non-triggered using DAC_Trigger_None
and DAC_OUT1/DAC_OUT2 is available once writing to DHRx register using
DAC_SetChannel1Data()/DAC_SetChannel2Data.
[..] Digital to Analog conversion can be triggered by:
(#) External event: EXTI Line 9 (any GPIOx_Pin9) using DAC_Trigger_Ext_IT9.
The used pin (GPIOx_Pin9) must be configured in input mode.
(#) Timers TRGO: TIM2, TIM8/TIM3, TIM4, TIM6, TIM7, and TIM15
(DAC_Trigger_T2_TRGO, DAC_Trigger_T4_TRGO...)
The timer TRGO event should be selected using TIM_SelectOutputTrigger()
(++) To trigger DAC conversions by TIM3 instead of TIM8 follow
this sequence:
(+++) Enable SYSCFG APB clock by calling
RCC_APB2PeriphClockCmd(RCC_APB2Periph_SYSCFG, ENABLE);
(+++) Select DAC_Trigger_T3_TRGO when calling DAC_Init()
(+++) Remap the DAC trigger from TIM8 to TIM3 by calling
SYSCFG_TriggerRemapConfig(SYSCFG_TriggerRemap_DACTIM3, ENABLE)
(#) Software using DAC_Trigger_Software
[..] Each DAC channel integrates an output buffer that can be used to
reduce the output impedance, and to drive external loads directly
without having to add an external operational amplifier.
To enable, the output buffer use
DAC_InitStructure.DAC_OutputBuffer = DAC_OutputBuffer_Enable;
[..] Refer to the device datasheet for more details about output impedance
value with and without output buffer.
[..] Both DAC channels can be used to generate:
(+) Noise wave using DAC_WaveGeneration_Noise
(+) Triangle wave using DAC_WaveGeneration_Triangle
[..] Wave generation can be disabled using DAC_WaveGeneration_None
[..] The DAC data format can be:
(+) 8-bit right alignment using DAC_Align_8b_R
(+) 12-bit left alignment using DAC_Align_12b_L
(+) 12-bit right alignment using DAC_Align_12b_R
[..] The analog output voltage on each DAC channel pin is determined
by the following equation:
(+) DAC_OUTx = VREF+ * DOR / 4095 with DOR is the Data Output Register.
VREF+ is the input voltage reference (refer to the device datasheet)
e.g. To set DAC_OUT1 to 0.7V, use DAC_SetChannel1Data(DAC_Align_12b_R, 868);
Assuming that VREF+ = 3.3, DAC_OUT1 = (3.3 * 868) / 4095 = 0.7V
[..] A DMA request can be generated when an external trigger (but not
a software trigger) occurs if DMA2 requests are enabled using
DAC_DMACmd();
DMA requests are mapped as following:
(+) DAC channel1 is mapped on DMA2 channel3 which must be already
configured.
(+) DAC channel2 is mapped on DMA2 channel4 which must be already
configured.
##### How to use this driver #####
===============================================================================
[..]
(+) DAC APB clock must be enabled to get write access to DAC
registers using RCC_APB1PeriphClockCmd(RCC_APB1Periph_DAC, ENABLE);
(+) Configure DAC_OUTx (DAC_OUT1: PA4, DAC_OUT2: PA5) in analog mode.
(+) Configure the DAC channel using DAC_Init();
(+) Enable the DAC channel using DAC_Cmd();

* functionalities of the Direct Memory Access controller (DMA):
* + Initialization and Configuration
* + Data Counter
* + Interrupts and flags management
*
@verbatim
===============================================================================
##### How to use this driver #####
===============================================================================
[..]
(#) Enable The DMA controller clock using
RCC_AHBPeriphClockCmd(RCC_AHBPeriph_DMA1, ENABLE) function for DMA1 or
using RCC_AHBPeriphClockCmd(RCC_AHBPeriph_DMA2, ENABLE) function for DMA2.
(#) Enable and configure the peripheral to be connected to the DMA channel
(except for internal SRAM / FLASH memories: no initialization is necessary).
(#) For a given Channel, program the Source and Destination addresses,
the transfer Direction, the Buffer Size, the Peripheral and Memory
Incrementation mode and Data Size, the Circular or Normal mode,
the channel transfer Priority and the Memory-to-Memory transfer
mode (if needed) using the DMA_Init() function.
(#) Enable the NVIC and the corresponding interrupt(s) using the function
DMA_ITConfig() if you need to use DMA interrupts.
(#) Enable the DMA channel using the DMA_Cmd() function.
(#) Activate the needed channel Request using PPP_DMACmd() function for
any PPP peripheral except internal SRAM and FLASH (ie. SPI, USART ...)
The function allowing this operation is provided in each PPP peripheral
driver (ie. SPI_DMACmd for SPI peripheral).
(#) Optionally, you can configure the number of data to be transferred
when the channel is disabled (ie. after each Transfer Complete event
or when a Transfer Error occurs) using the function DMA_SetCurrDataCounter().
And you can get the number of remaining data to be transferred using
the function DMA_GetCurrDataCounter() at run time (when the DMA channel is
enabled and running).
(#) To control DMA events you can use one of the following two methods:
(##) Check on DMA channel flags using the function DMA_GetFlagStatus().
(##) Use DMA interrupts through the function DMA_ITConfig() at initialization
phase and DMA_GetITStatus() function into interrupt routines in
communication phase.
After checking on a flag you should clear it using DMA_ClearFlag()
function. And after checking on an interrupt event you should
clear it using DMA_ClearITPendingBit() function.

The user should identify which mode will be used in his application to manage
the DMA controller events: Polling mode or Interrupt mode.
*** Polling Mode ***
====================
[..] Each DMA channel can be managed through 4 event Flags (y : DMA Controller
number, x : DMA channel number):
(#) DMAy_FLAG_TCx : to indicate that a Transfer Complete event occurred.
(#) DMAy_FLAG_HTx : to indicate that a Half-Transfer Complete event occurred.
(#) DMAy_FLAG_TEx : to indicate that a Transfer Error occurred.
(#) DMAy_FLAG_GLx : to indicate that at least one of the events described
above occurred.
[..]
(@) Clearing DMAy_FLAG_GLx results in clearing all other pending flags of the
same channel (DMAy_FLAG_TCx, DMAy_FLAG_HTx and DMAy_FLAG_TEx).
[..] In this Mode it is advised to use the following functions:
(+) FlagStatus DMA_GetFlagStatus(uint32_t DMA_FLAG);
(+) void DMA_ClearFlag(uint32_t DMA_FLAG);
*** Interrupt Mode ***
======================
[..] Each DMA channel can be managed through 4 Interrupts:
(+) Interrupt Source
(##) DMA_IT_TC: specifies the interrupt source for the Transfer Complete
event.
(##) DMA_IT_HT: specifies the interrupt source for the Half-transfer Complete
event.
(##) DMA_IT_TE: specifies the interrupt source for the transfer errors event.

* @brief This file provides firmware functions to manage the following
* functionalities of the EXTI peripheral:
* + Initialization and Configuration
* + Interrupts and flags management
*
@verbatim
===============================================================================
##### EXTI features #####
===============================================================================
[..] External interrupt/event lines are mapped as following:
(#) All available GPIO pins are connected to the 16 external
interrupt/event lines from EXTI0 to EXTI15.
(#) EXTI line 16 is connected to the PVD output
(#) EXTI line 17 is connected to the RTC Alarm event
(#) EXTI line 18 is connected to USB Device wakeup event
(#) EXTI line 19 is connected to the RTC Tamper and TimeStamp events
(#) EXTI line 20 is connected to the RTC wakeup event
(#) EXTI line 21 is connected to the Comparator 1 wakeup event
(#) EXTI line 22 is connected to the Comparator 2 wakeup event
(#) EXTI line 23 is connected to the I2C1 wakeup event
(#) EXTI line 24 is connected to the I2C2 wakeup event
(#) EXTI line 25 is connected to the USART1 wakeup event
(#) EXTI line 26 is connected to the USART2 wakeup event
(#) EXTI line 27 is reserved
(#) EXTI line 28 is connected to the USART3 wakeup event
(#) EXTI line 29 is connected to the Comparator 3 event
(#) EXTI line 30 is connected to the Comparator 4 event
(#) EXTI line 31 is connected to the Comparator 5 event
(#) EXTI line 32 is connected to the Comparator 6 event
(#) EXTI line 33 is connected to the Comparator 7 event
(#) EXTI line 34 is connected for thr UART4 wakeup event
(#) EXTI line 35 is connected for the UART5 wakeup event
##### How to use this driver #####
===============================================================================
[..] In order to use an I/O pin as an external interrupt source,
follow steps below:
(#) Configure the I/O in input mode using GPIO_Init().
(#) Select the input source pin for the EXTI line using
SYSCFG_EXTILineConfig().
(#) Select the mode(interrupt, event) and configure the trigger
selection (Rising, falling or both) using EXTI_Init(). For the
internal interrupt, the trigger selection is not needed
(the active edge is always the rising one).
(#) Configure NVIC IRQ channel mapped to the EXTI line using NVIC_Init().
(#) Optionally, you can generate a software interrupt using the function
EXTI_GenerateSWInterrupt().
[..]
(@) SYSCFG APB clock must be enabled to get write access to SYSCFG_EXTICRx
registers using RCC_APB2PeriphClockCmd(RCC_APB2Periph_SYSCFG, ENABLE);

* @brief This file provides firmware functions to manage the following
* functionalities of the GPIO peripheral:
* + Initialization and Configuration functions
* + GPIO Read and Write functions
* + GPIO Alternate functions configuration functions
*
* @verbatim
===============================================================================
##### How to use this driver #####
===============================================================================
[..]
(#) Enable the GPIO AHB clock using RCC_AHBPeriphClockCmd()
(#) Configure the GPIO pin(s) using GPIO_Init()
Four possible configuration are available for each pin:
(++) Input: Floating, Pull-up, Pull-down.
(++) Output: Push-Pull (Pull-up, Pull-down or no Pull),
Open Drain (Pull-up, Pull-down or no Pull).
In output mode, the speed is configurable: Low, Medium, Fast or High.
(++) Alternate Function: Push-Pull (Pull-up, Pull-down or no Pull),
Open Drain (Pull-up, Pull-down or no Pull).
(++) Analog: required mode when a pin is to be used as ADC channel,
DAC output or comparator input.
(#) Peripherals alternate function:
(++) For ADC, DAC and comparators, configure the desired pin in
analog mode using GPIO_InitStruct->GPIO_Mode = GPIO_Mode_AN
(++) For other peripherals (TIM, USART...):
(+++) Connect the pin to the desired peripherals' Alternate
Function (AF) using GPIO_PinAFConfig() function.
(+++) Configure the desired pin in alternate function mode using
GPIO_InitStruct->GPIO_Mode = GPIO_Mode_AF
(+++) Select the type, pull-up/pull-down and output speed via
GPIO_PuPd, GPIO_OType and GPIO_Speed members.
(+++) Call GPIO_Init() function.
(#) To get the level of a pin configured in input mode use GPIO_ReadInputDataBit()
(#) To set/reset the level of a pin configured in output mode use
GPIO_SetBits()/GPIO_ResetBits()
(#) During and just after reset, the alternate functions are not active
and the GPIO pins are configured in input floating mode (except JTAG pins).
(#) The LSE oscillator pins OSC32_IN and OSC32_OUT can be used as
general-purpose (PC14 and PC15, respectively) when the LSE
oscillator is off. The LSE has priority over the GPIO function.
(#) The HSE oscillator pins OSC_IN/OSC_OUT can be used as general-purpose
(PF0 and PF1 respectively) when the HSE oscillator is off. The HSE has
the priority over the GPIO function.

* @file stm32f30x_iwdg.c
* @author MCD Application Team
* @version V1.0.0
* @date 04-September-2012
* @brief This file provides firmware functions to manage the following
* functionalities of the Independent watchdog (IWDG) peripheral:
* + Prescaler and Counter configuration
* + IWDG activation
* + Flag management
*
@verbatim
===============================================================================
##### IWDG features #####
===============================================================================
[..] The IWDG can be started by either software or hardware (configurable
through option byte).
[..] The IWDG is clocked by its own dedicated low-speed clock (LSI) and
thus stays active even if the main clock fails.
Once the IWDG is started, the LSI is forced ON and cannot be disabled
(LSI cannot be disabled too), and the counter starts counting down from
the reset value of 0xFFF. When it reaches the end of count value (0x000)
a system reset is generated.
The IWDG counter should be reloaded at regular intervals to prevent
an MCU reset.
[..] The IWDG is implemented in the VDD voltage domain that is still functional
in STOP and STANDBY mode (IWDG reset can wake-up from STANDBY).
[..] IWDGRST flag in RCC_CSR register can be used to inform when a IWDG
reset occurs.
[..] Min-max timeout value @41KHz (LSI): ~0.1ms / ~25.5s
The IWDG timeout may vary due to LSI frequency dispersion. STM32F30x
devices provide the capability to measure the LSI frequency (LSI clock
connected internally to TIM16 CH1 input capture). The measured value
can be used to have an IWDG timeout with an acceptable accuracy.
For more information, please refer to the STM32F30x Reference manual.
##### How to use this driver #####
===============================================================================
[..] This driver allows to use IWDG peripheral with either window option enabled
or disabled. To do so follow one of the two procedures below.
(#) Window option is enabled:
(++) Start the IWDG using IWDG_Enable() function, when the IWDG is used
in software mode (no need to enable the LSI, it will be enabled
by hardware).
(++) Enable write access to IWDG_PR and IWDG_RLR registers using
IWDG_WriteAccessCmd(IWDG_WriteAccess_Enable) function.
(++) Configure the IWDG prescaler using IWDG_SetPrescaler() function.
(++) Configure the IWDG counter value using IWDG_SetReload() function.
This value will be loaded in the IWDG counter each time the counter
is reloaded, then the IWDG will start counting down from this value.
(++) Wait for the IWDG registers to be updated using IWDG_GetFlagStatus() function.
(++) Configure the IWDG refresh window using IWDG_SetWindowValue() function.
(#) Window option is disabled:
(++) Enable write access to IWDG_PR and IWDG_RLR registers using
IWDG_WriteAccessCmd(IWDG_WriteAccess_Enable) function.
(++) Configure the IWDG prescaler using IWDG_SetPrescaler() function.
(++) Configure the IWDG counter value using IWDG_SetReload() function.
This value will be loaded in the IWDG counter each time the counter
is reloaded, then the IWDG will start counting down from this value.
(++) Wait for the IWDG registers to be updated using IWDG_GetFlagStatus() function.
(++) reload the IWDG counter at regular intervals during normal operation
to prevent an MCU reset, using IWDG_ReloadCounter() function.
(++) Start the IWDG using IWDG_Enable() function, when the IWDG is used
in software mode (no need to enable the LSI, it will be enabled
by hardware).

function according to the following table.
The table below gives the allowed values of the pre-emption priority
and subpriority according to the Priority Grouping configuration
performed by NVIC_PriorityGroupConfig function.
(#) Enable and Configure the priority of the selected IRQ Channels.
[..]
(@) When the NVIC_PriorityGroup_0 is selected, it will no any nested interrupt,
the IRQ priority will be managed only by subpriority.
The sub-priority is only used to sort pending exception priorities,
and does not affect active exceptions.
(@) Lower priority values gives higher priority.
(@) Priority Order:
(#@) Lowest Preemption priority.
(#@) Lowest Subpriority.
(#@) Lowest hardware priority (IRQn position).

/** @defgroup PWR_Group4 Low Power modes configuration functions
* @brief Low Power modes configuration functions
*
@verbatim
===============================================================================
##### Low Power modes configuration functions #####
==============================================================================
[..] The devices feature three low-power modes:
(+) Sleep mode: Cortex-M4 core stopped, peripherals kept running.
(+) Stop mode: all clocks are stopped, regulator running, regulator in low power mode
(+) Standby mode: VCORE domain powered off
*** Sleep mode ***
==================
[..]
(+) Entry:
(++) The Sleep mode is entered by executing the WFE() or WFI() instructions.
(+) Exit:
(++) Any peripheral interrupt acknowledged by the nested vectored interrupt
controller (NVIC) can wake up the device from Sleep mode.
*** Stop mode ***
=================
[..] In Stop mode, all clocks in the VCORE domain are stopped, the PLL, the HSI,
and the HSE RC oscillators are disabled. Internal SRAM and register
contents are preserved.
The voltage regulator can be configured either in normal or low-power mode.
(+) Entry:
(++) The Stop mode is entered using the PWR_EnterSTOPMode(PWR_Regulator_LowPower,)
function with regulator in LowPower or with Regulator ON.
(+) Exit:
(++) Any EXTI Line (Internal or External) configured in Interrupt/Event mode
or any internal IPs (I2C or UASRT) wakeup event.
*** Standby mode ***
====================
[..] The Standby mode allows to achieve the lowest power consumption. It is based
on the Cortex-M4 deepsleep mode, with the voltage regulator disabled.
The VCORE domain is consequently powered off. The PLL, the HSI, and the HSE
oscillator are also switched off. SRAM and register
contents are lost except for the Backup domain (RTC registers, RTC backup
registers and Standby circuitry).
[..] The voltage regulator is OFF.
(+) Entry:
(++) The Standby mode is entered using the PWR_EnterSTANDBYMode() function.
(+) Exit:
(++) WKUP pin rising edge, RTC alarm (Alarm A and Alarm B), RTC wakeup,
tamper event, time-stamp event, external reset in NRST pin, IWDG reset.
*** Auto-wakeup (AWU) from low-power mode ***
=============================================
[..] The MCU can be woken up from low-power mode by an RTC Alarm event, a tamper
event, a time-stamp event, or a comparator event, without depending on an
external interrupt (Auto-wakeup mode).
(+) RTC auto-wakeup (AWU) from the Stop mode
(++) To wake up from the Stop mode with an RTC alarm event, it is necessary to:
(+++) Configure the EXTI Line 17 to be sensitive to rising edges (Interrupt
or Event modes) using the EXTI_Init() function.
(+++) Enable the RTC Alarm Interrupt using the RTC_ITConfig() function
(+++) Configure the RTC to generate the RTC alarm using the RTC_SetAlarm()
and RTC_AlarmCmd() functions.
(++) To wake up from the Stop mode with an RTC Tamper or time stamp event, it
is necessary to:
(+++) Configure the EXTI Line 19 to be sensitive to rising edges (Interrupt
or Event modes) using the EXTI_Init() function.
(+++) Enable the RTC Tamper or time stamp Interrupt using the RTC_ITConfig()
function.
(+++) Configure the RTC to detect the tamper or time stamp event using the
RTC_TimeStampConfig(), RTC_TamperTriggerConfig() and RTC_TamperCmd()
functions.
(+) RTC auto-wakeup (AWU) from the Standby mode
(++) To wake up from the Standby mode with an RTC alarm event, it is necessary to:
(+++) Enable the RTC Alarm Interrupt using the RTC_ITConfig() function.
(+++) Configure the RTC to generate the RTC alarm using the RTC_SetAlarm()
and RTC_AlarmCmd() functions.
(++) To wake up from the Standby mode with an RTC Tamper or time stamp event, it
is necessary to:
(+++) Enable the RTC Tamper or time stamp Interrupt using the RTC_ITConfig()
function.
(+++) Configure the RTC to detect the tamper or time stamp event using the
RTC_TimeStampConfig(), RTC_TamperTriggerConfig() and RTC_TamperCmd()
functions.
(+) Comparator auto-wakeup (AWU) from the Stop mode
(++) To wake up from the Stop mode with a comparator wakeup event, it is necessary to:
(+++) Configure the correspondant comparator EXTI Line to be sensitive to
the selected edges (falling, rising or falling and rising)
(Interrupt or Event modes) using the EXTI_Init() function.
(+++) Configure the comparator to generate the event.

******************************************************************************
* @file stm32f30x_wwdg.c
* @author MCD Application Team
* @version V1.0.0
* @date 04-September-2012
* @brief This file provides firmware functions to manage the following
* functionalities of the Window watchdog (WWDG) peripheral:
* + Prescaler, Refresh window and Counter configuration
* + WWDG activation
* + Interrupts and flags management
*
* @verbatim
*
==============================================================================
##### WWDG features #####
==============================================================================
[..] Once enabled the WWDG generates a system reset on expiry of a programmed
time period, unless the program refreshes the counter (downcounter)
before to reach 0x3F value (i.e. a reset is generated when the counter
value rolls over from 0x40 to 0x3F).
[..] An MCU reset is also generated if the counter value is refreshed
before the counter has reached the refresh window value. This
implies that the counter must be refreshed in a limited window.
[..] Once enabled the WWDG cannot be disabled except by a system reset.
[..] WWDGRST flag in RCC_CSR register can be used to inform when a WWDG
reset occurs.
[..] The WWDG counter input clock is derived from the APB clock divided
by a programmable prescaler.
[..] WWDG counter clock = PCLK1 / Prescaler.
[..] WWDG timeout = (WWDG counter clock) * (counter value).
[..] Min-max timeout value @36MHz (PCLK1): ~114us / ~58.3ms.
##### How to use this driver #####
==============================================================================
[..]
(#) Enable WWDG clock using RCC_APB1PeriphClockCmd(RCC_APB1Periph_WWDG, ENABLE)
function.
(#) Configure the WWDG prescaler using WWDG_SetPrescaler() function.
(#) Configure the WWDG refresh window using WWDG_SetWindowValue() function.
(#) Set the WWDG counter value and start it using WWDG_Enable() function.
When the WWDG is enabled the counter value should be configured to
a value greater than 0x40 to prevent generating an immediate reset.
(#) Optionally you can enable the Early wakeup interrupt which is
generated when the counter reach 0x40.
Once enabled this interrupt cannot be disabled except by a system reset.
(#) Then the application program must refresh the WWDG counter at regular
intervals during normal operation to prevent an MCU reset, using
WWDG_SetCounter() function. This operation must occur only when
the counter value is lower than the refresh window value,
programmed using WWDG_SetWindowValue().

* @author MCD Application Team
* @version V1.0.0
* @date 04-September-2012
* @brief CMSIS Cortex-M4 Device Peripheral Access Layer System Source File.
* This file contains the system clock configuration for STM32F30x devices,
* and is generated by the clock configuration tool
* stm32f30x_Clock_Configuration_V1.0.0.xls
*
* 1. This file provides two functions and one global variable to be called from
* user application:
* - SystemInit(): Setups the system clock (System clock source, PLL Multiplier
* and Divider factors, AHB/APBx prescalers and Flash settings),
* depending on the configuration made in the clock xls tool.
* This function is called at startup just after reset and
* before branch to main program. This call is made inside
* the "startup_stm32f30x.s" file.
*
* - SystemCoreClock variable: Contains the core clock (HCLK), it can be used
* by the user application to setup the SysTick
* timer or configure other parameters.
*
* - SystemCoreClockUpdate(): Updates the variable SystemCoreClock and must
* be called whenever the core clock is changed
* during program execution.
*
* 2. After each device reset the HSI (8 MHz) is used as system clock source.
* Then SystemInit() function is called, in "startup_stm32f30x.s" file, to
* configure the system clock before to branch to main program.
*
* 3. If the system clock source selected by user fails to startup, the SystemInit()
* function will do nothing and HSI still used as system clock source. User can
* add some code to deal with this issue inside the SetSysClock() function.
*
* 4. The default value of HSE crystal is set to 8MHz, refer to "HSE_VALUE" define
* in "stm32f30x.h" file. When HSE is used as system clock source, directly or
* through PLL, and you are using different crystal you have to adapt the HSE
* value to your own configuration.
*
* 5. This file configures the system clock as follows:
*=============================================================================
* Supported STM32F30x device
*-----------------------------------------------------------------------------
* System Clock source | PLL (HSE)
*-----------------------------------------------------------------------------
* SYSCLK(Hz) | 72000000
*-----------------------------------------------------------------------------
* HCLK(Hz) | 72000000
*-----------------------------------------------------------------------------
* AHB Prescaler | 1
*-----------------------------------------------------------------------------
* APB2 Prescaler | 1
*-----------------------------------------------------------------------------
* APB1 Prescaler | 2
*-----------------------------------------------------------------------------
* HSE Frequency(Hz) | 8000000
*----------------------------------------------------------------------------
* PLLMUL | 9
*-----------------------------------------------------------------------------
* PREDIV | 1
*-----------------------------------------------------------------------------
* USB Clock | DISABLE
*-----------------------------------------------------------------------------
* Flash Latency(WS) | 2
*-----------------------------------------------------------------------------
* Prefetch Buffer | ON
*-----------------------------------------------------------------------------
