(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 general purpose I/O port.

(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 HAK
pin.
HAK
In external bus mode, this pin functions as the hold acknowledge out-
put (HAK) pin. When the HDE bit in the EPCR register is set to “0”, this
pin functions as a general purpose I/O port.

(CMOS)
This is a general purpose I/O port. In external bus mode, when the
RYE bit in the EPCR register is set to “1”, this pin functions as the RDY
pin.
RDY
In external bus mode, this pin functions as the external ready (RDY)
input pin. When the RYE 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
CKE bit in the EPCR register is set to “1”, this pin functions as the CLK
pin.
CLK
In external bus mode, this pin functions as the machine cycle clock
(CLK) output pin. When the CKE bit in the EPCR register is set to
“0”, this pin functions as a general purpose I/O port.
