Example Description

This example describes how to use the HSE clock failure detection feature.

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.

Once the DCSS is enabled and if the HSE clock fails, the DCSS interrupt occurs and an NMI is automatically generated. In this example, LED1 blink when the DCSS event does not occur, LED2 blink after the DCSS event occurs.
