Figure 19.4
The above applies under the following conditions:
• The BFC bit in the TRCMR register is set to 1 (the TRCGRC register functions as the buffer register for the TRCGRA register).
• Bits IOA2 to IOA0 in the TRCIOR0 register are set to 001b (“L” output by compare match).
Make the following settings in timer mode.
• To use the TRCGRC register as the buffer register for the TRCGRA register:
• To use the TRCGRD register as the buffer register for the TRCGRB register:
The output compare function, PWM mode, or PWM2 mode, and the TRCGRC or TRCGRD register is
functioning as a buffer register, the IMFC bit or IMFD bit in the TRCSR register is set to 1 when a compare
match with the TRC register occurs.
The input capture function and the TRCGRC register or TRCGRD register is functioning as a buffer register,
the IMFC bit or IMFD bit in the TRCSR register is set to 1 at the input edge of a signal input to the TRCIOC pin
or TRCIOD pin.

TRCGRA register
Set the IOC2 bit in the TRCIOR1 register to the same value as the IOA2 bit in the TRCIOR0 register.
Set the IOD2 bit in the TRCIOR1 register to the same value as the IOB2 bit in the TRCIOR0 register.
