Function

General-purpose I/O port

This port is available when the UART (ch.2) serial data output

from SOD3 is disabled either in the single-chip mode or when the

upper address control register setting is “port.”

Output pin for external address bus A16

This pin is available when the UART (ch.2) serial data output

from SOD3 is disabled in an external-bus mode and when the

upper address control register setting is “address.”

UART (ch.2) serial data output pin (SOD3)

This pin is available when the UART (ch.2) serial data output is

enabled.

General-purpose I/O port

This port is available when the UART (ch.2) clock output is

disabled either in the single-chip mode or when the upper

address control register setting is “port.”

Output pin for external address bus A17

This pin is available when the UART (ch.2) clock output is

disabled in an external-bus mode and when the upper address

control register setting is “address.”

UART (ch.2) clock output pin (SCK2)

This pin is available when the UART (ch.2) clock output is

enabled.

UART (ch.2) external clock input pin (SCK2)

This pin is available when the port is in input mode and the UART

(ch.2) specification is external clock mode.

General-purpose I/O port

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

address control register setting is “port.”

Output pin for external address bus A18

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

address control register setting is “address.”

UART (ch.2) serial data input pin (SID2)

Since this input is used whenever the SID2 is in input operation,

the output by any other function must be suspended unless the

output is intentionally performed.

General-purpose I/O port

This port is available when the UART (ch.2) serial data output

from SOD2 is disabled either in the single-chip mode or when the

upper address control register setting is “port.”

Output pin for external address bus A19

This pin is available when the UART (ch.2) serial data output

from SOD2 is disabled in an external-bus mode and when the

upper address control register setting is “address.”

UART (ch.2) serial data output pin (SOD2)

This pin is available when the UART (ch.2) serial data output

from SOD2 is enabled.
