P120 is an I/O port with an output latch. Port 12 can be set to the input mode or output mode in 1-bit units using port
P121 to P124 are input ports.
This port can also be used for external interrupt request input, potential input for external low-voltage detection,
Reset signal generation sets port 12 to input mode.
Figures 5-22 to 5-24 show block diagrams of port 12.
Caution The function setting on P121 to P124 is available only once after the reset release. The port once set
for connection to an oscillator cannot be used as an input port unless the reset is performed.
