Circuit
General-purpose input/output port. It functions as the HAK pin in the
external bus mode if the HDE bit of the EPCR register is set to "1".
D
Functions as the hold acknowledge output (HAK) pin in the external
(CMOS)
bus mode, and functions as a general-purpose input/output port if the
HDE bit of the EPCR register is set to "0".
General-purpose input/output port. It functions as the RDY pin in the
external bus mode if the RYE bit of the PCR register is set to "1".
D
Functions as the external ready input (RDY) pin in the external bus
(CMOS)
mode, and functions as a general-purpose input/output port if the
RYE bit of the EPCR register is set to "0".
General-purpose input/output port. It functions as the CLK pin in the
external bus mode if the CKE bit of the EPCR register is set to "1".
D
Functions as the machine cycle clock output (CLK) pin in the external
(CMOS)
bus mode, and functions as a general-purpose input/output port if the
CKE bit of the EPCR register is set to "0".
