1.4 CCP Compare Mode
This example shows how to use the CCP module in compare mode to generate an dual edge, 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.
- Dual Edge output: Output is set high on compare A match and is set low on compare B match.
- Active high output: Output is set high on compare A match and remains high.
- Toggle output: Output toggles on compare A match.
