* @author MCD Application Team
* @brief CMSIS Cortex-M3 Device Peripheral Access Layer System Source File.
*
* 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
* factors, AHB/APBx prescalers and Flash settings).
* This function is called at startup just after reset and
* before branch to main program. This call is made inside
* the "startup_stm32f1xx_xx.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_stm32f1xx_xx.s" file, to
* configure the system clock before to branch to main program.
*
* 4. The default value of HSE crystal is set to 8 MHz (or 25 MHz, depending on
* the product used), refer to "HSE_VALUE".
* 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.

==============================================================================
##### How to use this driver #####
==============================================================================
[..]
The LL CORTEX driver contains a set of generic APIs that can be
used by user:
(+) SYSTICK configuration used by @ref LL_mDelay and @ref LL_Init1msTick
functions
(+) Low power mode configuration (SCB register of Cortex-MCU)
(+) MPU API to configure and enable regions
(MPU services provided only on some devices)
(+) API to access to MCU info (CPUID register)
(+) API to enable fault handler (SHCSR accesses)

##### Initialization and de-initialization functions #####
===============================================================================
[..] This section provides functions allowing to:
(+) Initializes the Flash interface, the NVIC allocation and initial clock
configuration. It initializes the systick also when timeout is needed
and the backup domain when enabled.
(+) de-Initializes common part of the HAL.
(+) Configure The time base source to have 1ms time base with a dedicated
Tick interrupt priority.
(++) SysTick timer is used by default as source of time base, but user
can eventually implement his proper time base source (a general purpose
timer for example or other time source), keeping in mind that Time base
duration should be kept 1ms since PPP_TIMEOUT_VALUEs are defined and
handled in milliseconds basis.
(++) Time base configuration function (HAL_InitTick ()) is called automatically
at the beginning of the program after reset by HAL_Init() or at any time
when clock is configured, by HAL_RCC_ClockConfig().
(++) Source of time base is configured to generate interrupts at regular
time intervals. Care must be taken if HAL_Delay() is called from a
peripheral ISR process, the Tick interrupt line must have higher priority
(numerically lower) than the peripheral interrupt. Otherwise the caller
ISR process will be blocked.
(++) functions affecting time base configurations are declared as __weak
to make override possible in case of other implementations in user file.

/**
* @brief This function is used to initialize the HAL Library; it must be the first

* Configure the Flash prefetch.
* Configures the SysTick to generate an interrupt each 1 millisecond,
* which is clocked by the HSI (at this stage, the clock is not yet
* configured and thus the system is running from the internal HSI at 16 MHz).

==============================================================================
##### How to use this driver #####
==============================================================================
[..]
*** How to configure Interrupts using CORTEX HAL driver ***
===========================================================
[..]
This section provides functions allowing to configure the NVIC interrupts (IRQ).
The Cortex-M3 exceptions are managed by CMSIS functions.
(#) Configure the NVIC Priority Grouping using HAL_NVIC_SetPriorityGrouping()
function according to the following table.
(#) Configure the priority of the selected IRQ Channels using HAL_NVIC_SetPriority().
(#) Enable the selected IRQ Channels using HAL_NVIC_EnableIRQ().
(#) please refer to programming manual for details in how to configure priority.
-@- When the NVIC_PRIORITYGROUP_0 is selected, IRQ preemption is no more possible.
The pending IRQ priority will be managed only by the sub priority.
-@- IRQ priority order (sorted by highest to lowest priority):
(+@) Lowest preemption priority
(+@) Lowest sub priority
(+@) Lowest hardware priority (IRQ number)
[..]
*** How to configure Systick using CORTEX HAL driver ***
========================================================
[..]
Setup SysTick Timer for time base.
(+) The HAL_SYSTICK_Config()function calls the SysTick_Config() function which
is a CMSIS function that:
(++) Configures the SysTick Reload register with value passed as function parameter.
(++) Configures the SysTick IRQ priority to the lowest value 0x0F.
(++) Resets the SysTick Counter register.
(++) Configures the SysTick Counter clock source to be Core Clock Source (HCLK).
(++) Enables the SysTick Interrupt.
(++) Starts the SysTick Counter.
(+) You can change the SysTick Clock source to be HCLK_Div8 by calling the macro
__HAL_CORTEX_SYSTICKCLK_CONFIG(SYSTICK_CLKSOURCE_HCLK_DIV8) just after the
HAL_SYSTICK_Config() function call. The __HAL_CORTEX_SYSTICKCLK_CONFIG() macro is defined
inside the stm32f1xx_hal_cortex.h file.
(+) You can change the SysTick IRQ priority by calling the
HAL_NVIC_SetPriority(SysTick_IRQn,...) function just after the HAL_SYSTICK_Config() function
call. The HAL_NVIC_SetPriority() call the NVIC_SetPriority() function which is a CMSIS function.
(+) To adjust the SysTick time base, use the following formula:
Reload Value = SysTick Counter Clock (Hz) x Desired Time base (s)
(++) Reload Value is the parameter to be passed for HAL_SYSTICK_Config() function
(++) Reload Value should not exceed 0xFFFFFF

* @brief DMA HAL module driver.
* This file provides firmware functions to manage the following
* functionalities of the Direct Memory Access (DMA) peripheral:
* + Initialization and de-initialization functions
* + IO operation functions
* + Peripheral State and errors functions
@verbatim
==============================================================================
##### How to use this driver #####
==============================================================================
[..]
(#) Enable and configure the peripheral to be connected to the DMA Channel
(except for internal SRAM / FLASH memories: no initialization is
necessary). Please refer to the Reference manual for connection between peripherals
and DMA requests.
(#) For a given Channel, program the required configuration through the following parameters:
Channel request, Transfer Direction, Source and Destination data formats,
Circular or Normal mode, Channel Priority level, Source and Destination Increment mode
using HAL_DMA_Init() function.
(#) Use HAL_DMA_GetState() function to return the DMA state and HAL_DMA_GetError() in case of error
detection.
(#) Use HAL_DMA_Abort() function to abort the current transfer
-@- In Memory-to-Memory transfer mode, Circular mode is not allowed.
*** Polling mode IO operation ***
=================================
[..]
(+) Use HAL_DMA_Start() to start DMA transfer after the configuration of Source
address and destination address and the Length of data to be transferred
(+) Use HAL_DMA_PollForTransfer() to poll for the end of current transfer, in this
case a fixed Timeout can be configured by User depending from his application.
*** Interrupt mode IO operation ***
===================================
[..]
(+) Configure the DMA interrupt priority using HAL_NVIC_SetPriority()
(+) Enable the DMA IRQ handler using HAL_NVIC_EnableIRQ()
(+) Use HAL_DMA_Start_IT() to start DMA transfer after the configuration of
Source address and destination address and the Length of data to be transferred.
In this case the DMA interrupt is configured
(+) Use HAL_DMA_IRQHandler() called under DMA_IRQHandler() Interrupt subroutine
(+) At the end of data transfer HAL_DMA_IRQHandler() function is executed and user can
add his own function by customization of function pointer XferCpltCallback and
XferErrorCallback (i.e. a member of DMA handle structure).
*** DMA HAL driver macros list ***
=============================================
[..]
Below the list of most used macros in DMA HAL driver.
(+) __HAL_DMA_ENABLE: Enable the specified DMA Channel.
(+) __HAL_DMA_DISABLE: Disable the specified DMA Channel.
(+) __HAL_DMA_GET_FLAG: Get the DMA Channel pending flags.
(+) __HAL_DMA_CLEAR_FLAG: Clear the DMA Channel pending flags.
(+) __HAL_DMA_ENABLE_IT: Enable the specified DMA Channel interrupts.
(+) __HAL_DMA_DISABLE_IT: Disable the specified DMA Channel interrupts.
(+) __HAL_DMA_GET_IT_SOURCE: Check whether the specified DMA Channel interrupt has occurred or not.
[..]
(@) You can refer to the DMA HAL driver header file for more useful macros

@verbatim
==============================================================================
##### EXTI Peripheral features #####
==============================================================================
[..]
(+) Each Exti line can be configured within this driver.
(+) Exti line can be configured in 3 different modes
(++) Interrupt
(++) Event
(++) Both of them
(+) Configurable Exti lines can be configured with 3 different triggers
(++) Rising
(++) Falling
(++) Both of them
(+) When set in interrupt mode, configurable Exti lines have two different
interrupts pending registers which allow to distinguish which transition
occurs:
(++) Rising edge pending interrupt
(++) Falling
(+) Exti lines 0 to 15 are linked to gpio pin number 0 to 15. Gpio port can
be selected through multiplexer.
##### How to use this driver #####
==============================================================================
[..]
(#) Configure the EXTI line using HAL_EXTI_SetConfigLine().
(++) Choose the interrupt line number by setting "Line" member from
EXTI_ConfigTypeDef structure.
(++) Configure the interrupt and/or event mode using "Mode" member from
EXTI_ConfigTypeDef structure.
(++) For configurable lines, configure rising and/or falling trigger
"Trigger" member from EXTI_ConfigTypeDef structure.
(++) For Exti lines linked to gpio, choose gpio port using "GPIOSel"
member from GPIO_InitTypeDef structure.
(#) Get current Exti configuration of a dedicated line using
HAL_EXTI_GetConfigLine().
(++) Provide exiting handle as parameter.
(++) Provide pointer on EXTI_ConfigTypeDef structure as second parameter.
(#) Clear Exti configuration of a dedicated line using HAL_EXTI_GetConfigLine().
(++) Provide exiting handle as parameter.
(#) Register callback to treat Exti interrupts using HAL_EXTI_RegisterCallback().
(++) Provide exiting handle as first parameter.
(++) Provide which callback will be registered using one value from
EXTI_CallbackIDTypeDef.
(++) Provide callback function pointer.
(#) Get interrupt pending bit using HAL_EXTI_GetPending().
(#) Clear interrupt pending bit using HAL_EXTI_GetPending().
(#) Generate software interrupt using HAL_EXTI_GenerateSWI().

* This file provides firmware functions to manage the following
* functionalities of the internal FLASH memory:
* + Program operations functions
* + Memory Control functions
* + Peripheral State functions
*
@verbatim
==============================================================================
##### FLASH peripheral features #####
==============================================================================
[..] The Flash memory interface manages CPU AHB I-Code and D-Code accesses
to the Flash memory. It implements the erase and program Flash memory operations
and the read and write protection mechanisms.
[..] The Flash memory interface accelerates code execution with a system of instruction
prefetch.
[..] The FLASH main features are:
(+) Flash memory read operations
(+) Flash memory program/erase operations
(+) Read / write protections
(+) Prefetch on I-Code
(+) Option Bytes programming
##### How to use this driver #####
==============================================================================
[..]
This driver provides functions and macros to configure and program the FLASH
memory of all STM32F1xx devices.
(#) FLASH Memory I/O Programming functions: this group includes all needed
functions to erase and program the main memory:
(++) Lock and Unlock the FLASH interface
(++) Erase function: Erase page, erase all pages
(++) Program functions: half word, word and doubleword
(#) FLASH Option Bytes Programming functions: this group includes all needed
functions to manage the Option Bytes:
(++) Lock and Unlock the Option Bytes
(++) Set/Reset the write protection
(++) Set the Read protection Level
(++) Program the user Option Bytes
(++) Launch the Option Bytes loader
(++) Erase Option Bytes
(++) Program the data Option Bytes
(++) Get the Write protection.
(++) Get the user option bytes.
(#) Interrupts and flags management functions : this group
includes all needed functions to:
(++) Handle FLASH interrupts
(++) Wait for last FLASH operation according to its status
(++) Get error flag status
[..] In addition to these function, this driver includes a set of macros allowing
to handle the following operations:
(+) Set/Get the latency
(+) Enable/Disable the prefetch buffer
(+) Enable/Disable the half cycle access
(+) Enable/Disable the FLASH interrupts
(+) Monitor the FLASH flags status

* @brief GPIO HAL module driver.
* This file provides firmware functions to manage the following
* functionalities of the General Purpose Input/Output (GPIO) peripheral:
* + Initialization and de-initialization functions
* + IO operation functions
*
@verbatim
==============================================================================
##### GPIO Peripheral features #####
==============================================================================
[..]
Subject to the specific hardware characteristics of each I/O port listed in the datasheet, each
port bit of the General Purpose IO (GPIO) Ports, can be individually configured by software
in several modes:
(+) Input mode
(+) Analog mode
(+) Output mode
(+) Alternate function mode
(+) External interrupt/event lines
[..]
During and just after reset, the alternate functions and external interrupt
lines are not active and the I/O ports are configured in input floating mode.
[..]
All GPIO pins have weak internal pull-up and pull-down resistors, which can be
activated or not.
[..]
In Output or Alternate mode, each IO can be configured on open-drain or push-pull
type and the IO speed can be selected depending on the VDD value.
[..]
All ports have external interrupt/event capability. To use external interrupt
lines, the port must be configured in input mode. All available GPIO pins are
connected to the 16 external interrupt/event lines from EXTI0 to EXTI15.
[..]
The external interrupt/event controller consists of up to 20 edge detectors in connectivity
line devices, or 19 edge detectors in other devices for generating event/interrupt requests.
Each input line can be independently configured to select the type (event or interrupt) and
the corresponding trigger event (rising or falling or both). Each line can also masked
independently. A pending register maintains the status line of the interrupt requests
##### How to use this driver #####
==============================================================================
[..]
(#) Enable the GPIO APB2 clock using the following function : __HAL_RCC_GPIOx_CLK_ENABLE().
(#) Configure the GPIO pin(s) using HAL_GPIO_Init().
(++) Configure the IO mode using "Mode" member from GPIO_InitTypeDef structure
(++) Activate Pull-up, Pull-down resistor using "Pull" member from GPIO_InitTypeDef
structure.
(++) In case of Output or alternate function mode selection: the speed is
configured through "Speed" member from GPIO_InitTypeDef structure
(++) Analog mode is required when a pin is to be used as ADC channel
or DAC output.
(++) In case of external interrupt/event selection the "Mode" member from
GPIO_InitTypeDef structure select the type (interrupt or event) and
the corresponding trigger event (rising or falling or both).
(#) In case of external interrupt/event mode selection, configure NVIC IRQ priority
mapped to the EXTI line using HAL_NVIC_SetPriority() and enable it using
HAL_NVIC_EnableIRQ().
(#) To get the level of a pin configured in input mode use HAL_GPIO_ReadPin().
(#) To set/reset the level of a pin configured in output mode use
HAL_GPIO_WritePin()/HAL_GPIO_TogglePin().
(#) To lock pin configuration until next reset use HAL_GPIO_LockPin().
(#) 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 PD0 and PD1, respectively, when the HSE oscillator is off.
The HSE has priority over the GPIO function.

* @brief Low Power modes configuration functions
*
@verbatim
===============================================================================
##### Peripheral Control functions #####
===============================================================================
*** PVD configuration ***
=========================
[..]
(+) The PVD is used to monitor the VDD power supply by comparing it to a
threshold selected by the PVD Level (PLS[2:0] bits in the PWR_CR).
(+) A PVDO flag is available to indicate if VDD/VDDA is higher or lower
than the PVD threshold. This event is internally connected to the EXTI
line16 and can generate an interrupt if enabled. This is done through
__HAL_PVD_EXTI_ENABLE_IT() macro.
(+) The PVD is stopped in Standby mode.
*** WakeUp pin configuration ***
================================
[..]
(+) WakeUp pin is used to wake up the system from Standby mode. This pin is
forced in input pull-down configuration and is active on rising edges.
(+) There is one WakeUp pin:
WakeUp Pin 1 on PA.00.
[..]
*** Low Power modes configuration ***
=====================================
[..]
The device features 3 low-power modes:
(+) Sleep mode: CPU clock off, all peripherals including Cortex-M3 core peripherals like
NVIC, SysTick, etc. are kept running
(+) Stop mode: All clocks are stopped
(+) Standby mode: 1.8V domain powered off
*** Sleep mode ***
==================
[..]
(+) Entry:
The Sleep mode is entered by using the HAL_PWR_EnterSLEEPMode(PWR_MAINREGULATOR_ON, PWR_SLEEPENTRY_WFx)
functions with
(++) PWR_SLEEPENTRY_WFI: enter SLEEP mode with WFI instruction
(++) PWR_SLEEPENTRY_WFE: enter SLEEP mode with WFE instruction
(+) Exit:
(++) WFI entry mode, Any peripheral interrupt acknowledged by the nested vectored interrupt
controller (NVIC) can wake up the device from Sleep mode.
(++) WFE entry mode, Any wakeup event can wake up the device from Sleep mode.
(+++) Any peripheral interrupt w/o NVIC configuration & SEVONPEND bit set in the Cortex (HAL_PWR_EnableSEVOnPend)
(+++) Any EXTI Line (Internal or External) configured in Event mode
*** Stop mode ***
=================
[..]
The Stop mode is based on the Cortex-M3 deepsleep mode combined with peripheral
clock gating. The voltage regulator can be configured either in normal or low-power mode.
In Stop mode, all clocks in the 1.8 V domain are stopped, the PLL, the HSI and the HSE RC
oscillators are disabled. SRAM and register contents are preserved.
In Stop mode, all I/O pins keep the same state as in Run mode.
(+) Entry:
The Stop mode is entered using the HAL_PWR_EnterSTOPMode(PWR_REGULATOR_VALUE, PWR_SLEEPENTRY_WFx )
function with:
(++) PWR_REGULATOR_VALUE= PWR_MAINREGULATOR_ON: Main regulator ON.
(++) PWR_REGULATOR_VALUE= PWR_LOWPOWERREGULATOR_ON: Low Power regulator ON.
(++) PWR_SLEEPENTRY_WFx= PWR_SLEEPENTRY_WFI: enter STOP mode with WFI instruction
(++) PWR_SLEEPENTRY_WFx= PWR_SLEEPENTRY_WFE: enter STOP mode with WFE instruction
(+) Exit:
(++) WFI entry mode, Any EXTI Line (Internal or External) configured in Interrupt mode with NVIC configured
(++) WFE entry mode, Any EXTI Line (Internal or External) configured in Event mode.
*** Standby mode ***
====================
[..]
The Standby mode allows to achieve the lowest power consumption. It is based on the
Cortex-M3 deepsleep mode, with the voltage regulator disabled. The 1.8 V domain is
consequently powered off. The PLL, the HSI oscillator and the HSE oscillator are also
switched off. SRAM and register contents are lost except for registers in the Backup domain
and Standby circuitry
(+) Entry:
(++) The Standby mode is entered using the HAL_PWR_EnterSTANDBYMode() function.
(+) Exit:
(++) WKUP pin rising edge, RTC alarm event rising edge, external Reset in
NRSTpin, IWDG Reset
*** Auto-wakeup (AWU) from low-power mode ***
=============================================
[..]
(+) The MCU can be woken up from low-power mode by an RTC Alarm event,
without depending on an external interrupt (Auto-wakeup mode).
(+) RTC auto-wakeup (AWU) from the Stop and Standby modes
(++) To wake up from the Stop mode with an RTC alarm event, it is necessary to
configure the RTC to generate the RTC alarm using the HAL_RTC_SetAlarm_IT() function.
*** PWR Workarounds linked to Silicon Limitation ***
====================================================

Below the list of all silicon limitations known on STM32F1xx prouct.
