1.16 OCMP Compare Mode
This example application shows how to use the OCMP peripheral to generate an active low, active high, and toggle output on compare match.
Description
In this application, three OCMP modules are used to generate waveforms.
Active Low Output: By default output is set as high and it is set as low on the compare match
Active High Output: By default output is set as low and it is set as high on the compare match
