PF1
PF2
This register sets the pin functions of P13/TxD0/KR4/<TxD6> pins.
PF1 is set using a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets PF1 to 00H.
Remark
This register sets whether to use pins P20 to P25 as port pins (other than segment output pins) or segment
output pins.
PF2 is set using a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets PF2 to 00H.
