2. When selecting 1 (The TRDGRDi register is used as a buffer register of TRDGRBi register) for this bit by the BFDi bit
0
When selecting 1 (The TRDGRCi register is used as a buffer register of the TRDGRAi register) for this bit by the BFCi
bit in the TRDMR register, set the IOC2 bit in the TRDIORCi register to the same as the IOA2 bit in the TRDIORAi
register.
in the TRDMR register, set the IOD2 bit in the TRDIORCi register to the same as the IOB2 bit in the TRDIORAi register.
