Function

General-purpose I/O port

This port is available in the single-chip mode and when the CLK

output is disabled.

CLK output pin

This pin is available in an external-bus mode with the CLK output

enabled.

General-purpose I/O port

This port is available in the single-chip mode or when the ready

function is disable.

Ready signal input pin

This pin is available in an external-bus mode and when the ready

function is enabled.

General-purpose I/O port

This port is available in the single-chip mode or when the hold

function is disabled.

Hold acknowledge output pin

This pin is available in an external-bus mode and when the hold

function is enabled.

General-purpose I/O port

This port is available in the single-chip mode or when the hold

function is disabled in an external-bus mode.

Hold request input pin

This pin is available in an external-bus mode and when the hold

function is enabled.

Since this input is used during this operation at any time, the

output by any other function must be suspended unless the

output is intentionally performed.

General-purpose I/O port

This port is available in the single-chip mode, in the external bus

8-bit mode, or when the WRH pin output is disabled.

When these pins are open in input mode, through current may

leak in stop mode/reset mode, be sure to fix these pins to VCC/VSS

level to use these pins in input mode.

UART (ch.0) clear-to-send input pin

Since this input is used whenever the UART (ch.0) CTS function

is enabled, the output by any other function must be suspended

unless the output is intentionally performed.

When these pins are open in input mode, through current may

leak in stop mode/reset mode, be sure to fix these pins to VCC/VSS

level to use these pins in input mode.

Write strobe output pin for the upper eight bits of data bus

This pin is available in the external bus 16-bit mode with the

WRH pin output enabled in an external-bus mode.
