Section 8 I/O Ports
8.4
8.4.1
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/2138 Group only), and as data bus I/O pins. Port 3 functions change according to the
operating mode. Port 3 has an on-chip MOS input pull-up function that can be controlled by
software.
Figure 8.9 shows the port 3 pin configuration.
