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.)
In multiplex mode, these pins function as the external address/data bus
low I/O pins.
In non-multiplex mode, these pins function as the external data bus low
output pins.
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.)
In multiplex mode, these pins function as the external address/data bus
high I/O pins.
In non-multiplex mode, these pins function as the external data bus high
output pins.
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.
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.
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).
