(3) Port mode register 12 (PM12)
When using the P120/EXLVI/INTP0 pin for external low-voltage detection potential input, set PM120 to 1. At this
time, the output latch of P120 may be 0 or 1.
PM12 can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets this register to FFH.
