Example Description

This example describes how to enters the system to STANDBY mode and wake-up from this mode.

In this example, Main clock is from PLL clock and it is configured at 96MHz. The PLL clock is based on 8MHz HSE. APB1 and APB2 clock is from Main clock.

This example turns on LED1, waits for a period of time and then enables the WKUP pin and enters the STANDBY mode. The system enters STANDBY mode causing the LED1 turns off. Than can wake-up STANDBY mode by pressing a button connected to the WKUP pin or a RESET button. After wake-up from STANDBY mode, program execution restarts in the same way as after a RESET, the RTC configuration (clock source, prescaler,...) is kept and LED1 restarts toggling. As result there is no need to configure the RTC.
