Circuit
type
This is a general purpose I/O port. In external bus mode, when
P56 the RYE bit in the EPCR register is set to "1", this pin functions
as the RDY pin.
D
(CMOS)
In external bus mode, this pin functions as the external ready
RDY (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.
This is a general purpose I/O port. In external bus mode, when
P57 the CKE bit in the EPCR register is set to "1", this pin functions
as the CLK pin.
D
(CMOS)
In external bus mode, this pin functions as the machine cycle
CLK 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.
These are general purpose I/O ports.
