25.3.3 Channels vs. Pin outs

As the TCC module may have more waveform output pins than the number of compare/capture channels, the free pins (with number higher than number of channels) will reuse the waveform generated by channels subsequently. E.g., if the number of channels is four and the number of wave output pins is eight, channel 0 output will be available on out pin 0 and 4, channel 1 output on wave out pin 1 and 5, and so on.
