16.4.1
In this mode, an internally generated count source or the timer RJ underflow is counted. Registers TRBOCR
and TRBSC are not used.
When 1 (count starts) is written to the TSTART bit in the TRBCR register, the count is started. When 0 (count
stops) is written to the TSTART bit, the count is stopped. When 1 (count is forcibly stopped) is written to the
TSTOP bit in the TRBCR register, the count is stopped.
An interrupt request is generated when timer RB2 underflows.
When registers TRBPRE and TRBPR are read, each count value can be read. When registers TRBPRE and
TRBPR are written while the count is stopped, values are written to both the reload register and counter,
respectively. When these registers are written during count operation, the reload register is written. A program
can be used to select whether values are transferred to the counter at the next count operation, or written to the
reload register only and then transferred to the counter at the next reload operation.
Figure 16.2 shows an Operation Example in Timer Mode.
Note:
Operation
1. The count is started after three cycles of the count source when the TSTART bit is set.
Timer Mode
Monitor the TCSTF bit in the TRBCR register to confirm the operating state of the counter.
