15.4.3 Output Data Buffer Register (OPDBR)
The Output Data Buffer Register is composed of twelve registers (OPDBRB to
OPDBR0). The value of the OPDBRx register specified by the BNKF, RDA2 to RDA0 bits
is loaded into the OPDR register at the rising edge of the write signal generated by the
Data Write Control Unit.
