(2) Buffer Operation
The TRDGRCi register (i = 0 or 1) can be used as the buffer register for the TRDGRAi register, and the TRDGRDi
register can be used as the buffer register for the TRDGRBi register by means of bits TRDBFCi and TRDBFDi in the
TRDMR register.
 TRDGRAi buffer register: TRDGRCi register
 TRDGRBi buffer register: TRDGRDi register
Buffer operation depends on the mode. Table 8-12 lists the Buffer Operation in Each Mode.
