P120 functions as an I/O port with an output latch. P120 can be set to the input mode or output mode in 1-bit units
P121 to P125 function as an Input port.
When used as an input port for P120 and P125, use of an on-chip pull-up resistor can be specified by pull-up resistor
This port can also be used as pins for external interrupt request input, potential input for external low-voltage detection,
The timer input and external interrupt request input can be assigned to P121 of the 78K0/KA2-L (25-pin products) and
Set bit 5 (RSTM) of the reset pin mode register (RSTMASK) to 1 when using P125/RESET as an input port, and clear
Reset signal generation sets port 12 to input mode.
Figures 4-27 to 4-29 show block diagrams of port 12.
