Section 8 I/O Ports

8.1 Overview

The H8/3864 Series is provided with six 8-bit I/O ports, one 4-bit I/O port, one 3-bit I/O port, one 8-
bit input-only port, and one 1-bit input-only port. Table 8-1 indicates the functions of each port.

Each port has of a port control register (PCR) that controls input and output, and a port data register
(PDR) for storing output data. Input or output can be assigned to individual bits.
See 2.9.2, Notes on Bit Manipulation, for information on executing bit-manipulation instructions to
write data in PCR or PDR.

Ports 5, 6, 7, 8, and A are also used as liquid crystal display segment and common pins, selectable
in 8-bit units.

Block diagrams of each port are given in Appendix C, I/O Port Block Diagrams.
