WR0

P84

External bus write strobe output.

This function is valid in external bus mode.

D

General-purpose I/O port.

This function is valid in single-chip mode.

WR1

External bus write strobe output.

This function is valid when WR1 output in external bus mode

is enabled.

169

50

Input capture input pin.

IN3

D

Since this input is always used when it is selected for input

capture input, output using the port must be stopped before-

hand unless this operation is the intended operation.

General-purpose I/O port.

P85

This function is valid when external bus write enable output is

disabled.

System clock output.

SYSCLK

This function is valid when system clock output is enabled. A

clock having the same frequency as the external bus operat-

170

62

C ing frequency is output (stopped in stop mode).

P90

General-purpose I/O port.

This function is valid when system clock output is disabled.

171

63

P91

C General-purpose I/O port

172

⎯
