Change bits TMOD1 and TMOD0; TCK1 and TCK0; and TCKCUT w hen both the TSTART and TCSTF bits in the TRBCR
register set to 0 (count stops).
The TWRC bit can be set to either 0 or 1 in timer mode. In programmable w aveform generation mode, programmable
one-shot generation mode, or programmable w ait one-shot generation mode, the TWRC bit must be set to 1 (w rite to
reload register only).
