Function as a data input pin for UART ch.1.

General purpose input/output port.

G Function as the external address pin in non-multi-bus mode.

Function as a data output pin for UART ch.1.

General purpose input/output port.

G Function as the external address pin in non-multi-bus mode.

Function as a clock I/O pin for UART ch.1.

General purpose input/output port.

L

Function as the address latch enable signal pin in external bus mode.

General purpose input/output port.

L

Function as the read strobe output pin in external bus mode.

General purpose input/output port.

L Function as the data write strobe output pin on the lower side in external

bus mode. This pin functions as a general-purpose I/O port when the WRE

bit in the EPCR register is “0”.

General purpose input/output port.

L Function as the data write strobe output pin on the higher side in bus width

16-bit external bus mode. This pin functions as a general-purpose I/O port

when the WRE bit in the EPCR register is “0”.

General purpose input/output port.

L Function as the hold request input pin in external bus mode. This pin

functions as a general-purpose I/O port when the HDE bit in the EPCR

register is “0”.

General purpose input/output port.

L Function as the hold acknowledge output pin in external bus mode. This pin

functions as a general-purpose I/O port when the HDE bit in the EPCR

register is “0”.

General purpose input/output port.

L Function as the external ready input pin in external bus mode. This pin

functions as a general-purpose I/O port when the RYE bit in the EPCR

register is “0”.

General purpose input/output port.

L Function as the machine cycle clock output pin in external bus mode. This

pin functions as a general-purpose I/O port when the CKE bit in the EPCR

register is “0”.

General purpose input/output port. (With stand voltage of 5 V)

C

Function as external interrupt ch.0 and ch.1 input pins.
