mbed_official | 5:ac9f6c2c45e8 | 4 | * @author MCD Application Team |
mbed_official | 5:ac9f6c2c45e8 | 5 | * @version V2.2.2 |
mbed_official | 5:ac9f6c2c45e8 | 6 | * @date 26-June-2015 |
mbed_official | 5:ac9f6c2c45e8 | 7 | * @brief CMSIS Cortex-M0 Device Peripheral Access Layer System Source File. |
mbed_official | 5:ac9f6c2c45e8 | 8 | * |
mbed_official | 5:ac9f6c2c45e8 | 9 | * 1. This file provides two functions and one global variable to be called from |
mbed_official | 5:ac9f6c2c45e8 | 10 | * user application: |
mbed_official | 5:ac9f6c2c45e8 | 11 | * - SystemInit(): This function is called at startup just after reset and |
mbed_official | 5:ac9f6c2c45e8 | 12 | * before branch to main program. This call is made inside |
mbed_official | 5:ac9f6c2c45e8 | 13 | * the "startup_stm32f0xx.s" file. |
mbed_official | 5:ac9f6c2c45e8 | 14 | * |
mbed_official | 5:ac9f6c2c45e8 | 15 | * - SystemCoreClock variable: Contains the core clock (HCLK), it can be used |
mbed_official | 5:ac9f6c2c45e8 | 16 | * by the user application to setup the SysTick |
mbed_official | 5:ac9f6c2c45e8 | 17 | * timer or configure other parameters. |
mbed_official | 5:ac9f6c2c45e8 | 18 | * |
mbed_official | 5:ac9f6c2c45e8 | 19 | * - SystemCoreClockUpdate(): Updates the variable SystemCoreClock and must |
mbed_official | 5:ac9f6c2c45e8 | 20 | * be called whenever the core clock is changed |
mbed_official | 5:ac9f6c2c45e8 | 21 | * during program execution. |
mbed_official | 5:ac9f6c2c45e8 | 22 | * |
mbed_official | 5:ac9f6c2c45e8 | 23 | * 2. After each device reset the HSI (8 MHz) is used as system clock source. |
mbed_official | 5:ac9f6c2c45e8 | 24 | * Then SystemInit() function is called, in "startup_stm32f0xx.s" file, to |
mbed_official | 5:ac9f6c2c45e8 | 25 | * configure the system clock before to branch to main program. |
mbed_official | 5:ac9f6c2c45e8 | 26 | * |
mbed_official | 5:ac9f6c2c45e8 | 27 | * 3. This file configures the system clock as follows: |
