# 1.3 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.
