85 to 92 83 to 90
P00 to P07
C
(CMOS)
This is a general purpose I/O port. A setting in the port 0 input
resistance register (RDR0) can be used to apply pull-up resistance
(RD00-RD07
=
“1”) . (Disabled when pin is set for output.)
In multiplex mode, these pins function as the external address/data
bus low I/O pins.
AD00 to
AD07
D00 to D07
In non-multiplex mode, these pins function as the external data bus
low output pins.

C
(CMOS)
This is a general purpose I/O port. A setting in the port 1 input
resistance register (RDR1) can be used to apply pull-up resistance
(RD10-RD17
=
“1”) . (Disabled when pin is set for output.)
In multiplex mode, these pins function as the external address/data
bus high I/O pins.
AD08 to
AD15
D08 to D15
In non-multiplex mode, these pins function as the external data bus
high output pins.

E
(

H
)
This is a general purpose I/O port. When the bits of external address
output control register (HACR) are set to "1" in external bus mode,
these pins function as general purpose I/O ports.
A16 to A19
When the bits of external address output control register (HACR) are
set to "0" in multiplex mode, these pins function as address high
output pins (A16-A19).
When the bits of external address output control register (HACR) are
set to "0" in non-multiplex mode, these pins function as address high
output pins (A16-A19).

This is a general purpose I/O port. When the bits of external address
output control register (HACR) are set to "1" in external bus mode,
these pins function as general purpose I/O ports.
A20 to A23
When the bits of external address output control register (HACR) are
set to "0" in multiplex mode, these pins function as address high
output pins (A20-A23).
When the bits of external address output control register (HACR) are
set to "0" in non-multiplex mode, these pins function as address high
output pins (A20-A23).
