I/O Area and I/O Allocations
Section 4-2
Example 2: Connecting Expansion I/O Units with Only Inputs or Only
Outputs
If Expansion I/O Units with only inputs or only outputs are connected, the
input or output word not used by an Expansion I/O Unit is allocated to the next
Unit that requires it.
4-2-4
I/O Word Allocations to Expansion Units
m:
Indicates the next input word after the input word allocated to the
Expansion Unit, Expansion I/O Unit, or CPU Unit to the left of the cur-
rent Unit.
n:
Indicates the next output word after the output word allocated to the
Expansion Unit, Expansion I/O Unit, or CPU Unit to the left of the cur-
rent Unit.
