In the 8-bit timer with 8-bit prescaler, the 8-bit TRBPR register is used to set the period of the counter and the
primary period. When read, the value is read from the 8-bit counter.
In the 16-bit timer, the 8-bit TRBPR register is used to set the period of the higher 8-bit counter and the primary
period. When read, the value is read from the higher 8 bits of the 16-bit timer. Access the TRBPRE register and
then the TRBPR register.
The TRBPR register is configured with a master – reload register structure, so the reload register is written
simultaneously while the count is stopped. During the counter operation, the timing for updating the reload
register differs in each mode. For details, refer to Table 16.6 Reload Register Update Timing for Registers
TRBPR and TRBSC in 8-Bit Timer with 8-Bit Prescaler, and Table 16.7 Reload Register Update Timing
for Registers TRBPRE, TRBPR, and TRBSC in 16-Bit Timer.
If 1 (count is forcibly stopped) is written to the TSTOP bit in the TRBCR register, the TRBPR register is
initialized (FFh).
