A 32-kHz oscillation pin
B Reset input pin
General-purpose input/output port.
With a register for pull-up resistor settings (RDR0), a pull-up resistor
can be set to the enabled state (RD00-07="1") (disabled for the
output setting).
C
(CMOS) Functions as the lower input/output pin of an external address and
data bus in the multiplex mode.
Functions as the lower output pin of an external data bus in the non-
multiplex mode.
General-purpose input/output port.
With a register for pull-up resistor settings (RDR1), a pull-up resistor
is set to the enabled state (RD10-17="1") (disabled for the output
setting).
C
(CMOS) Functions as the upper input/output pin of an external address and
data bus in the multiplex mode.
Functions as the upper output pin of an external data bus in the non-
multiplex mode.
General-purpose input/output port.
Functions as the general-purpose input/output port in the external bus
mode if the bit corresponding to external address output control
register (HACR) is set to "1".
E Functions as the upper output pin of an address (A16 to A19) in the
(CMOS/H) multiplex mode if the bit corresponding to external address output
control register (HACR) is set to "0".
Functions as the upper output pin of an address (A16 to A19) in the
non-multiplex mode if the bit corresponding to external address output
control register (HACR) is set to "0".
