Note:

With both HSI and HSE clock sources, if the system clock frequency is equal to or less than

8 MHz, the PLL is turned off.

The Wakeup push-button of the STM3210B-EVAL board (connected to pin PA0 in the

STM32F10xxx) is used as the wakeup source for all low-power modes.

●

stm32f10x_it.c file:

This file manages the interrupt service routine of the EXTI line 0 if the selected way of

entering the low-power mode is the WFI instruction.
