Set the TRDSTR register using the MOV instruction (do not use the bit handling instruction). Refer to 14.3.12.1
TRDSTR Register of Notes on Timer RD.
When the CSEL0 bit is set to 1, w rite 0 to the TSTART0 bit.
When the CSEL1 bit is set to 1, w rite 0 to the TSTART1 bit.
When the CSEL0 bit is set to 0 and generating the compare match signal(TRDIOA0), this bit is set to 0 (count stops).
When the CSEL1 bit is set to 0 and generating the compare match signal(TRDIOA1), this bit is set to 0 (count stops).
