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/2648, H8S/2648R, H8S/2647, port D pins also
function as LCD driver output pins (SEG16 to SEG9).
Port D has a built-in MOS input pull-up function that can be controlled by software.
Figure 9-10 shows the port D pin configuration.
Note: * In the H8S/2648, H8S/2648R, and H8S/2647.
