Description

LQFP

QFP

P54

(CMOS)

General purpose input/output port. In external bus mode, this

pin functions as the HRQ pin when the HDE bit in the EPCR

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 input/output port.

P55

(CMOS)

General purpose input/output port. In external bus mode, this

pin functions as the HAK pin when the HDE bit in the EPCR

HAK

In external bus mode, this pin functions as the hold acknowl-

edge output (HAK) pin. When the HDE bit in the EPCR register

is set to “0”,this pin functions as a general purpose input/output

port.

P56

(CMOS)

General purpose input/output port. In external bus mode, this

pin functions as the DRY pin when the RYE bit in the EPCR

RDY

In external bus mode, this pin functions as the external ready

input (RDY) pin. When the RYE bit in the EPCR register is set

to “0”,this pin functions as a general purpose input/output port.

P57

(CMOS)

General purpose input/output port. In external bus mode, this

pin functions as the CLK pin when the CKE bit in the EPCR

CLK

In external bus mode, this pin functions as the machine cycle

clock output (CLK) pin. When the CKE bit in the EPCR register

is set to “0”,this pin functions as a general purpose input/output

port.
