Test input pin
This pin must always be fixed to “H”.

General-purpose I/O ports
Pull-up resistors can be set (RD07 to RD00 = “1”) using the
pull-up resistor setting register (RDR0).
The setting does not apply for ports set as outputs (D07 to D00
= “1”: invalid at the output setting).
In external bus mode, the pins function as the lower data I/O or
lower address outputs (AD00 to AD07).
General-purpose I/O ports
Pull-up resistors can be set (RD17 to RD10 = “1”) using the
pull-up resistor setting register (RDR1).
The setting does not apply for ports set as outputs (D17 to D10
= “1”: invalid at the output setting).
In 16-bit external bus mode, the pins function as the upper data
I/O or middle address outputs (AD08 to AD15).
General-purpose I/O ports
In external bus mode, pins for which the corresponding bit in
the HACR register is “0” function as the P20 to P27 pins.
In external bus mode, pins for which the corresponding bit in
the HACR register is “1” function as the upper address output
pins (A16 to A23).
General-purpose I/O port
Functions as the ALE pin in external bus mode.
Functions as the address latch enable signal.
General-purpose I/O port
Functions as the RD pin in external bus mode.
Functions as the read strobe output (RD).
General-purpose I/O port
Functions as the WRL pin in external bus mode if the WRE bit
in the ECSR register is “1”.
Functions as the lower data write strobe output (WRL).
