8.1
The H8/3644 Group is provided with three 8-bit I/O ports, three 5-bit I/O ports, two 3-bit I/O
ports, and one 8-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 section 2.9.2, Notes on Bit Manipulation, for information on executing bit-manipulation
instructions to write data in PCR or PDR.
Block diagrams of each port are given in appendix C, I/O Port Block Diagrams.
