(1) Port mode
P60 to P67 function as an 8-bit I/O port. P60 and P61, P64 to P67 pins also function as serial interface data I/O,
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, external interrupt request
The following operation modes can be specified in 1-bit units.
P50 to P57 function as external expansion I/O.
(a) EX8 to EX15
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).
P60 and P61, P64 to P67 function as serial interface data I/O, clock I/O, read strobe signal output, write strobe
signal output, and address strobe signal output.
(a) SDA0
(b) SCL0
(c) RD
(d) WR0
(e) WR1
(f) ASTB
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).
These are the external expansion I/O (multiplexed address/data bus, address bus, data bus) pins.
This is a serial data I/O pin of serial interface IIC0.
This is a serial clock I/O pin of serial interface IIC0.
This is a read strobe signal output pin.
This is a write strobe signal output (8-bit bus mode, 16-bit bus mode (lower byte)) pin.
This is a write strobe signal output (16-bit bus mode (higher byte)) pin.
This is an address strobe signal output pin.
