Bits are allocated to a Y CPU Unit in discontinuous positions, as shown in the
figure below, due to allocations for the pulse I/O terminals.

As shown above, a total of 12 input bits in CIO 0 and CIO 1 are allocated for
the Y CPU Unit. Unused bits in CIO 0 and CIO 1 are always cleared and can-
not be used as work bits.

There are Expansion I/O Units for expanding inputs, for expanding outputs,
and for expanding both input and outputs. I/O bits starting from bit 00 in the
