8.1
The H8/3834 Series is provided with eight 8-bit I/O ports, one 4-bit I/O port, one 3-bit I/O port,
one 8-bit input-only port, one 4-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, 9, and A double as liquid crystal display segment pins and common pins. The
choice of pin functions can be made in 4-bit groupings.
Block diagrams of each port are given in Appendix C, I/O Port Block Diagrams.
