4.2.9 Port 12
using port mode register 12 (PM12). When used as an input port, use of an on-chip pull-up resistor can be specified
by pull-up resistor option register 12 (PU12).
connecting resonator for main system clock, connecting resonator for subsystem clock, and external clock input for
main system clock.

P121 to P124 are 4-bit 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 4-23 to 4-25 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
P120 is a 1-bit I/O port with an output latch. Port 12 can be set to the input mode or output mode in 1-bit units
