P56
RDY
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.
D
(CMOS) 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.
76
78
P57
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.
D
(CMOS) In external bus mode, this pin functions as the machine cycle clock (CLK)
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.
