Note m: “m” denotes the last input word allocated to the CPU Unit, or to the previous
Expansion Unit or Expansion I/O Unit if one is already connected.
n: “n” denotes the last output word allocated to the CPU Unit, or to the previous
Expansion Unit or Expansion I/O Unit if one is already connected.
Expansion I/O Unit Allocation
•
In the following diagrams, shaded areas indicate bits actually used for inputs or
outputs.
•
Input bits are allocated to Expansion I/O Units starting from word (m+1), where
“m” is the last input word allocated to the CPU Unit, or to the previous Expan-
sion Unit or Expansion I/O Unit if one is already connected.
•
Output bits are allocated to Expansion I/O Units starting from word (n+1),
where “n” is the last output word allocated to the CPU Unit, or to the previous
Expansion Unit or Expansion I/O Unit if one is already connected.
