  This example is based on the GD32M531R-EVAL-V1.2 board, it shows how to use EVIC software
events to trigger GPIO output specific levels .

  EVIC is configured as:
  - PF12 is selected as single I/O
  - Software generate event signal
  When the event signal arrives, the PF12 pin level is reversed.

  After system start-up, the PF12 pin level reverses every 100ms, and it can be observed through the oscilloscope.
