In timer mode, a count source which is internally generated or timer RA underflows are counted (refer to Table
14.7 Specifications of Timer Mode). Registers TRBOCR and TRBSC are not used in timer mode.
Figure 14.16 shows the TRBIOC Register in Timer Mode.

f1, f2, f8, timer RA underflow
• Decrement
• When the timer underflows, it reloads the reload register contents before the
1/(n+1)(m+1)
1 (count starts) is written to the TSTART bit in the TRBCR register.
• 0 (count stops) is written to the TSTART bit in the TRBCR register.
• 1 (count forcibly stop) is written to the TSTOP bit in the TRBCR register.

Programmable I/O port or INT0 interrupt input
The count value can be read out by reading registers TRBPR and TRBPRE.
• When registers TRBPRE and TRBPR are written while the count is stopped,
• When registers TRBPRE and TRBPR are written to while count operation is
count continues (when timer RB underflows, the contents of timer RB primary
reload register is reloaded).
values are written to both the reload register and counter.
in progress:
If the TWRC bit in the TRBMR register is set to 0, the value is written to both
the reload register and the counter.
If the TWRC bit is set to 1, the value is written to the reload register only.
(Refer to 14.2.1.1 Timer Write Control during Count Operation.)
