In the following diagrams, shaded areas indicate bits actually used for inputs or
outputs.
Input bits are allocated starting from IR 00000.
Output bits are allocated starting from IR 01000.
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.
