P120 functions as a 1-bit I/O port. This pin also functions as a pin for external interrupt request input.
The following operation modes can be specified.
P130 functions as a 1-bit output-only port.
This is the A/D converter reference voltage input pin.
When the A/D converter is not used, connect this pin directly to EV
Note Connect port 2 directly to EV
This is the A/D converter ground potential pin. Even when the A/D converter is not used, always use this pin with
This is the active-low system reset input pin.
These are the pins for connecting a resonator for X1 input clock.
When supplying an external clock, input a signal to the X1 pin and input the inverse signal to the X2 pin.
These are the pins for connecting a resonator for subsystem clock.
When supplying an external clock, input a signal to the XT1 pin and input the inverse signal to the XT2 pin.

P120 functions as a 1-bit I/O port. P120 can be set to input or output using port mode register 12 (PM12). Use of
an on-chip pull-up resistor can be specified by pull-up resistor option register 12 (PU12).
P120 functions as an external interrupt request input pin (INTP0) for which the valid edge (rising edge, falling
edge, or both rising and falling edges) can be specified.
