When the BFC bit in the TRCMR register is set to 1 (buffer register of TRCGRA register), set the IOC2 bit in the
TRCIOR1 register to the same value as the IOA2 bit in the TRCIOR0 register.
When the BFD bit in the TRCMR register is set to 1 (buffer register of TRCGRB register), set the IOD2 bit in the
TRCIOR1 register to the same value as the IOB2 bit in the TRCIOR0 register.
