I/O Area and I/O Allocations Section 4-2
4-2-2 Allocations to Built-in General Purpose I/O on the CPU Unit
The bits that are allocated depend on the model of CPU Unit, as shown in the
following figures.
Allocations for X and XA CPU Units (24 Inputs/16 Outputs)
Bits are allocated for X and XA CPU Units as shown in the following figure.
Input Bit Allocations
For X and XA CPU Units, a total of 24 input bits are allocated: 12 bits in CIO 0
from bit 00 to bit 11 and 12 bits in CIO 1 from bit 00 to bit 11. Bits 12 to 15 in
CIO 0 and CIO 1 are always cleared and cannot be used as work bits.
Output Bit Allocations
For X and XA CPU Units, a total of 16 output bits are allocated: eight bits in
CIO 100 from bit 00 to bit 07 and eight bits in CIO 101 from bit 00 to bit 07.
Bits 08 to 15 in CIO 100 and CIO 101 can be used as work bits.
