29.8.10 Initial Value until Compare Match and Active Polarity at Compare Match in
The pulse width for the input capture signal must be at least three cycles of the timer RC operating clock.
The value of the TRCCNT register is transferred to the TRCGRi register after one or two cycles of the timer RC
operating clock after the input capture signal is input to the TRCIOi pin (i = A, B, C, or D) (when there is no
digital filter).
When the CSTP bit in the TRCCR2 register is 1 (increment stops), do not set the TRCMR register when a
compare match occurs between registers TRCCNT and TRCGRA.
Count source fHOCO can be used within the power supply voltage range Vcc = 2.7 V to 5.5 V. At voltages
besides these, do not set bits CKS2 to CKS0 in the TRCCR1 register to 110b (fHOCO).
After timer RC count is stopped, either switch to or cancel module standby. The timer RC module standby bit
exists in the MSTCR2 register.
• When switching modes during operation, set the CTS bit in the TRCMR register to 0 (count stops) before
• After switching modes, set the interrupt register to 0 before starting operation.
For TRCIOB, TRCIOC, and TRCIOD output, if the initial value until compare match is the same as the set
value for the active polarity at compare match, the compare match output is actually performed, but the initial
value seems to be retained because the output value does not change.
