Load Immediate Formatted (LDIF)
The Load Immediate Formatted instruction loads a 1–32 bit binary
value into the accumulator. The value reflects the current status of
the input module(s)
at the time the instruction is executed
.
Accumulator bits that are not used by the instruction are set to zero.
In the following example, when C0 is on, the binary pattern of X10–X17 will be loaded into
the accumulator using the Load Immediate Formatted instruction. The Out Immediate
Formatted instruction could be used to copy the specified number of bits in the accumulator
to the specified outputs on the output module, such as Y30–Y37. This technique is useful to
quickly copy an input pattern to outputs (without waiting for the CPU scan).
