P120 functions as a 1-bit I/O port. P121 to P124 function as a 4-bit input port. These pins also function as external
The following operation modes can be specified in 1-bit units.
(d) INTP3, INTP7
(e) PGAI
P120 functions as a 1-bit I/O port. P120 can be set to input or output port 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).
P121 to P124 function as a 4-bit input port.
P120 to P124 function as external interrupt request input, potential input for external low-voltage detection,
connecting resonator for main system clock, connecting resonator for subsystem clock, and external clock input
for main system clock.
(a) INTP0, INTP4, INTP5
These are the external interrupt request input pin for which the valid edge (rising edge, falling edge, or both
rising and falling edges) can be specified.
This is an programmable gain amplifier input pin.
In products other than the 78K0R/IB3 and the 38-pin products of the 78K0R/IC3, INTP4 and INTP5 are
shared with P70 and P71, respectively.
This is an external interrupt request input pin for which the valid edge (rising edge, falling edge, or both rising
and falling edges) can be specified.
