T3CM2 contains the mask bits for the match event of Counter 3 compare register 2
The compare registers and corresponding counter reset masks can be used to program the
counter time intervals and the toggle masks can be used to program the output signal. The sin-
gle-action mask can also be used in this mode. It starts operating after the timer started with
T3R.
