1.24 TC Compare Mode
This example shows how to use the TC module in Compare mode to generate an active-low, active-high, and toggle output on compare match.
Description
Three TC channels are configured in Compare mode. Each channel generates different output waveform depending upon configured action on compare match and period match.
Active-low output: Output is set high on compare 1 match and is set low on compare 0 match.
Active-high output: Output is set low on compare 1 match and is set high on compare 0 match.
Toggle output: Output toggles on compare 0 match.
