Timer mode is mode to count a count source which is internally generated or timer RA underflow (see Table
14.7 Timer Mode Specifications). The TRBOCR and TRBSC registers are unused in timer mode.
Figure 14.17 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)
n: setting value in TRBPRE register, m: setting value in TRBPR register
Write 1 (count starts) to the TSTART bit in the TRBCR register
• Write 0 (count stops) to the TSTART bit in the TRBCR register
• Write 1 (count forcibly stop) to the TSTOP bit in the TRBCR register
When timer RB underflows [timer RB interrupt]
Programmable I/O port
Programmable I/O port or INT0 interrupt input
The count value can be read out by reading the TRBPR and TRBPRE registers
• When registers TRBPRE and TRBPR are written while the count is stopped,
• When registers TRBPRE and TRBPR are written to while count operation is in
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.
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.
