This is a general purpose I/O port. In external bus mode, this pin functions as
the ALE pin.
In external bus mode, this pin functions as the address load enable (ALE) sig-
nal pin.
This is a general purpose I/O port. In external bus mode, this pin functions as
the RD pin.
In external bus mode, this pin functions as the read strobe output (RD) signal
pin.
This is a general purpose I/O port. In external bus mode, when the WRE pin
in the EPCR register is set to “1”, this pin functions as the WRL pin.
In external bus mode, this pin functions as the lower data write strobe output
(WRL) pin. When the WRE bit in the EPCR register is set to “0”, this pin func-
tions as a general purpose I/O port.
This is a general purpose I/O port. In external bus mode with 16-bit bus width,
when the WRE bit in the EPCR register is set to “1”, this pin functions as the
WRH pin.
In external bus mode with 16-bit bus width, this pin
functions as the upper data write strobe output (WRH) pin. When the WRE bit
in the EPCR register is set to “0”, this pin functions as a general purpose I/O
port.
This is a general purpose I/O port. In external bus mode, when the HDE bit in
the EPCR register is set to “1”, this pin functions as the HRQ pin.
In external bus mode, this pin functions as the hold request input (HRQ) pin.
When the HDE bit in the EPCR register is set to “0”, this pin functions as a gen-
eral purpose I/O port.
This is a general purpose I/O port. In external bus mode, when the HDE bit in
the EPCR register is set to “1”, this pin functions as the HAK pin.
In external bus mode, this pin functions as the hold
acknowledge (HAK) pin. When the HDE bit in the EPCR register is set to “0”,
this pin functions as a general purpose I/O port.
