Caution
This register sets port 1 input/output in 1-bit units.
When using the P13/TxD0/KR4/TxD6 pin for serial interface data output, clear PM13 to 0. The output latch of
P13 at this time may be 0 or 1.
When using the P12/RxD0/KR3/R
this time may be 0 or 1.
PM1 can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets this register to FFH.

PM1
This register sets the pin functions of P13/TxD0/KR4/TxD6 pin.
PF1 is set using a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets PF1 to 00H.
