P40 to P43 function as a 4-bit I/O port. P40 to P43 can be set to input or output port in 1-bit units using port mode
P50 to P53 function as a 4-bit I/O port. P50 to P53 can be set to input or output port in 1-bit units using port mode
P60 to P63 function as a 4-bit I/O port. These pins also function as pins for serial interface data I/O, clock I/O, and
The following operation modes can be specified in 1-bit units.
P70 to P77 function as an 8-bit I/O port. These pins also function as key interrupt input pins.
The following operation modes can be specified in 1-bit units.
P60 to P63 function as a 4-bit I/O port. P60 to P63 can be set to input port or output port in 1-bit units using port
mode register 6 (PM6).
Output of P60 to P63 is N-ch open-drain output (6 V tolerance).
P60 to P63 function as serial interface data I/O, clock I/O, and external clock input.

P70 to P77 function as an 8-bit I/O port. P70 to P77 can be set to input or output port in 1-bit units using port
mode register 7 (PM7). Use of an on-chip pull-up resistor can be specified by pull-up resistor option register 7
(PU7).
P70 to P77 function as key interrupt input pins.
Remarks 1. For the product ranks, consult an NEC Electronics sales representative.
This is a serial data I/O pin for serial interface IIC0.
This is a serial clock I/O pin for serial interface IIC0.
This is an external clock input pin to serial interface IIC0. To input an external clock, input a clock of 6.4 MHz.
