   This demo is based on the GD32G553Q-EVAL-V1.0 board, it shows how to configure
the comparator port output.

  CMP0 is configured as following:
  - Inverting input is internally connected to VREFINT = 1.2V.
  - Non Inverting input is connected to PB1.
  - Output is internally connected to port output(PA6).

  Connect PA6 to LED2(PE4), then LED2 will turn on and off when the CMP0 output
level changes.
  While PB1 is lower than VREFINT(1.2V), PA6 output low and LED2 is off.
  While PB1 is higher than VREFINT, PA6 output high and LED2 is on.
