Function
General purpose I/O port. The register can be set to select whether to use
a pull-up resistor. This function is enabled in single-chip mode.
Input/output pin for external bus address data bus bit 15.
This function is enabled when external bus is enabled.
General purpose I/O ports. The register can be set to select whether to use
a pull-up resistor. In external bus mode, the pin is enabled as a general-
purpose I/O port when the corresponding bit in the external address output
control register (HACR) is 1.

Output pins for A16 to A19 of the external address bus.
When the corresponding bit in the external address output control register
(HACR) is 0, the pins are enabled as high address output pins A16 to A19.
Output pins for PPGs.
General purpose I/O port. The register can be set to select whether to use
a pull-up resistor. In external bus mode, the pin is enabled as a general-
purpose I/O port when the corresponding bit in the external address output
control register (HACR) is 1.
Output pins for A20 of the external address bus. When the corresponding
bit in the external address output control register (HACR) is 0, the pin is
enabled as high address output pins A20.
Data sample input pin for input capture ICU0.
General purpose I/O port. The register can be set to select whether to use
a pull-up resistor. In external bus mode, the pin is enabled as a general-
purpose I/O port when the corresponding bit in the external address output
control register (HACR) is 1.
