9.11 Port D
9.11.1 Overview
Port D is an 8-bit I/O port. Port D has a data bus I/O function, and the pin functions change according to the operating
mode. In the H8S/2352, port D pins are dedicated data bus pins.
Port D has a on-chip MOS input pull-up function that can be controlled by software (on-chip ROM version only).
Figure 9-19 shows the port D pin configuration.
