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.
Note: * Modes 2, 3, 6, and 7 only apply to the H8S/2351.
