This section starts with the timing of the timer counter and general output
timing behaviour. Then, examples of output signal generation with and without
1-bit addition are presented.
The free running up counter is clocked by the timer count clock selected in
register MCNTCnm.
The counting operation is enabled or disabled by the MCNTCnm.PCE bit.
