Example Description

This example describes how to enters the STOP mode and wake-up from this mode using external interrupt.

In this example：

1. Turn on HSE to use it as the clock source of PLL and the PLL clock used as the main clock is set to 96 MHz.
2. LED1 turn on, LED2 turn off.
3. waits for a period of time, PA0 pin is configured to generate an interrupt on rising edge and enters the STOP mode.
4. Wake-up the STOP mode in external interrupt by pressing a button connected to PA0 pin.
5. LED2 is toggled In EXTI0 interrupt （LED2 turn on）.
6. When enters the STOP mode,the RTC configuration is not kept,so there is need to configure the RTC.
7. LED1 toggling.
