IR bits are allocated to actual input terminals and output terminals on the CPU
Board and Expansion I/O Boards. IR words that are not allocated to inputs or
outputs can be used as work words.
CPU Board inputs are allocated input bits in IR words IR 000 to IR 001 and
CPU Board outputs are allocated output bits in IR words IR 010 to IR 011. The
bit allocations are shown in detail in the following diagrams.

1. The unused bits in IR 000 and IR 001 cannot be used as work bits.
2. IR 00108 to IR 00111 are used as an input DIP switch.
