General-purpose I/O port.

This function is enabled in single-chip mode

Hold request input pin.

This function is enabled in an external-bus enabled mode.

General-purpose I/O port.

This function is enabled in single-chip mode.

Hold acknowledge output pin.

This function is enabled in an external-bus enabled mode.

General-purpose I/O port.

This function is enabled in single-chip mode.

Ready signal input pin.

This function is enabled in an external-bus enabled mode.

General-purpose I/O port.

This function is enabled in single-chip mode.

CLK output pin.

This function is enabled in an external-bus enabled mode.

General-purpose I/O port.

Serves as an open-drain output port (OD40 = 1) depending on the

setting of the open-drain control setting register (ODR4).

(D40 = 0: Disabled when the port is set for input.)

UART serial clock I/O pin.

This function is enabled with the UART clock output enabled.

General-purpose I/O port.

Serves as an open-drain output port (OD41 = 1) depending on the

setting of the open-drain control setting register (ODR4).

(D41 = 0: Disabled when the port is set for input.)

UART serial data output pin.

This function is enabled with the UART serial data output enabled.

General-purpose I/O port.

Serves as an open-drain output port (OD42 = 1) depending on the

setting of the open-drain control setting register (ODR4).

(D42 = 0: Disabled when the port is set for input.)

UART serial data input pin. Since this input is used as required while

the UART is operating for input, the output by any other function

must be off unless used intentionally.

General-purpose I/O port.

Serves as an open-drain output port (OD43 = 1) depending on the

setting of the open-drain control setting register (ODR4).

(D43 = 0: Disabled when the port is set for input.)

Extended I/O serial clock I/O pin. This function is enabled with the

extended I/O serial clock output enabled.
