2.2.5 P40 to P47 (port 4)
P40 to P47 function as an 8-bit I/O port. P40 to P47 can be set to input or output port in 1-bit units using port mode
register 4 (PM4). Use of an on-chip pull-up resistor can be specified by pull-up resistor option register 4 (PU4).
2.2.6 P50 to P57 (port 5)
P50 to P57 function as an 8-bit I/O port. P50 to P57 can be set to input or output port in 1-bit units using port mode
register 5 (PM5). Use of an on-chip pull-up resistor can be specified by pull-up resistor option register 5 (PU5).
2.2.7 P60 to P67 (port 6)
P60 to P67 function as an 8-bit I/O port. These pins also function as pins for serial interface data I/O, clock I/O,
and external clock input.
The following operation modes can be specified in 1-bit units.
(1) Port mode
P60 to P67 function as an 8-bit I/O port. P60 to P67 can be set to input port or output port in 1-bit units using port
mode register 6 (PM6). Only for P64 to P67, use of an on-chip pull-up resistor can be specified by pull-up resistor
option register 6 (PU6).
Output of P60 to P63 is N-ch open-drain output (6 V tolerance).
(2) Control mode
P60 to P67 function as serial interface data I/O, clock I/O, and external clock input.
(a) SDA0
This is a serial data I/O pin for serial interface IIC0.
(b) SCL0
This is a serial clock I/O pin for serial interface IIC0.
(c) EXSCL0
This is an external clock input pin to serial interface IIC0. To input an external clock, input a clock of 6.4
MHz.
2.2.8 P70 to P77 (port 7)
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.
(1) Port mode
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).
(2) Control mode
P70 to P77 function as key interrupt input pins.
(a) KR0 to KR7
These are the key interrupt input pins
