  This example is based on the GD32G553Q-EVAL-V1.0 board, it shows how to output CMP0_OUT 
by using CMP and TRIGSEL. TRIGSEL select CMP0_OUT as trigger source, then the CMP0_OUT is 
output to TRGSEL_OUT0 (PA15). 

  PA1 is CMP pulse input, PA15 is TRGSEL_OUT0 pin.
  In this demo, Connect PA15 to LED1. If input 3.3V to PA1, LED1 is on.
If input GND to PA1, LED1 is off.
