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.
In the following diagrams, shaded areas indicate bits actually used for inputs or
outputs.
Input bits are allocated to Expansion I/O Units from word (m+1), where "m" is
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.
Output bits are allocated to Expansion I/O Units 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.
Bits in the output words that are not used as output bits can be used as work
bits.
Bits in the input words that are not used as input bits cannot be used as work
bits.
