(CMOS)
This is a general purpose I/O port. A setting in the pull-up
resistance setting register (RDR0) can be used to apply pull-up
resistance (RD00-RD07
= “1”) . (Disabled when pin is set for
output.)
AD00 to AD07
In multiplex mode, these pins function as the external address/
data bus low I/O pins.
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 pull-up
resistance setting resister (RDR1) can be used to apply pull-up
resistance (RD10-RD17
= “1”) . (Disabled when pin is set for
output.)
AD08 to AD15
In multiplex mode, these pins function as the external address/
data bus high I/O pins.
D08 to D15
In non-multiplex mode, these pins function as the external data
bus high output pins.

E
(CMOS/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).
A16 to 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).

E
(CMOS/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.
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).
A20 to 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).
