I/O Area and I/O Allocations Section 4-2
I/O Unit, or CPU Unit are automatically allocated. This word is indicated as
“CIO m” for input words and as “CIO n” for output words.
■ I/O Bit Addresses
Units 8 Input Points (CP1W-8ED)
Eight input bits are allocated in one word (bits 00 to 07 in CIO m).
Only one word (8 bits) is allocated to an 8-input Expansion Input Unit. No out-
put words are allocated. Input bits 08 to 15 are always cleared by the system
and cannot be used as work bits.
Units with 8 Output Points (CP1W-8E
)
Eight output bits are allocated in one word (bits 00 to 07 in CIO n+1).
Only one word (8 bits) is allocated to an 8-output Expansion Output Unit. No
input words are allocated. Output bits 08 to 15 can be used as work bits.
