Port 3 is an 8-bit I/O port. Port 3 pins also function as host data bus I/O pins (HDB7 to HDB0)
(H8S/2148 Group and H8S/2147N only), and as data bus I/O pins. Port 3 functions change
according to the operating mode. Port 3 has a built-in MOS input pull-up function that can be
controlled by software.
Figure 8.9 shows the port 3 pin configuration.
