Load Immediate (LDI)
The Load Immediate instruction loads a 16-bit V-memory
value into the accumulator. The valid address range includes all
input point addresses on the local base. The value reflects the
current status of the input points at the time the instruction is
executed. This instruction may be used instead of the LDIF
instruction which requires you to specify the number of input points.
In the following example, when C0 is on, the binary pattern of X0–X17 will be loaded into
the accumulator using the Load Immediate instruction. The Out Immediate instruction
could be used to copy the 16 bits in the accumulator to output points, such as Y40–Y57. This
technique is useful to quickly copy an input pattern to output points (without waiting for a
full CPU scan to occur).
