|

* 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.
