P52
D
(CMOS)
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.
WRL
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.

P53
D
(CMOS)
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.
WRH
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.

D
(CMOS)
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.
HRQ
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.
