HD6432351 Datasheet, PDF (395/989 Pages) Renesas Technology Corp – The H8S/2000 CPU has an internal 32-bit architecture, is provided with sixteen 16-bit general registers and a concise

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. However, in the H8S/2350, port D pins function only as data bus
pins.
Port D has a built-in MOS input pull-up function that can be controlled by software (H8S/2351
only).
Figure 9-19 shows the port D pin configuration.
