P60 to P67 function as an 8-bit I/O port. These pins also function as control pins in external memory expansion
The following operation modes can be specified.
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.
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.
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).
P60 to P63 are N-ch open-drain pins. Use of an on-chip pull-up resistor can be specified by a mask option only
for mask ROM versions.
Use of an on-chip pull-up resistor can be specified for P64 to P67 by pull-up resistor option register 6 (PU6).
P64 to P67 function as control signal output pins (RD, WR, WAIT, ASTB) in external memory expansion mode.
Cautions 1. P66 functions as an I/O port if the external wait is not used in external memory expansion
P70 to P77 function as an 8-bit I/O port. P70 to P77 can be set to input or output 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.
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.
