When the TSTOP bit in the TRBCR register is set to 1, the TRBPR register is set to FFh.
The TRBRCSR register selects which pin is assigned to the timer RB and timer RC I/O. To use the I/O pin for
timer RB and timer RC, set this register.
Set the TRBOSEL0 bit before setting the timer RB associated registers. Set bits TRCCLKSEL0 and
TRCCLKSEL1 before setting the timer RC associated registers. Also, do not change the setting values of the
TRBOSEL0 bit during timer RB operation. Do not change the setting values of bits TRCCLKSEL0 and
TRCCLKSEL1 during timer RC operation.
