16.4.1 Timer counter
CNT0
This section starts with the timing of the timer counter and general output timing behaviour. Then, examples of
The free running up counter is clocked by the timer count clock selected in register MCNTC0.
The counting operation is enabled or disabled by the MCNTC0.PCE bit.

Timer counter starts with value 00H. Depending on bit MCNTC0.FULL, all following counter cycles start
with 00H or 01H, respectively.
Enable counting operation (MCNTC0.PCE = 1)
Disable counting operation (MCNTC0.PCE = 0)
Counting is stopped and timer counter is set to 00H.
