NOTE: Status flags are valid only until another instruction uses the same flag.
In the following example, when X1 is on, the Load Formatted instruction loads the binary
value (6) from C10–C13 into the accumulator. The CMPF instruction compares the value
in the accumulator to the value in Y20–Y23 (E hex). The corresponding discrete status flag
will be turned on, indicating the result of the comparison. In this example, if the value in the
accumulator is less than the value specified in the Compare instruction, SP60 will turn on
energizing C30.

Compare Formatted (CMPF)
The Compare Formatted instruction compares the value in the
accumulator with a specified number of discrete locations (1–32).
The instruction requires a starting location (Aaaa) and the number
of bits (Kbbb) to be compared. The corresponding status flag will
be turned on, indicating the result of the comparison. The data
format for this instruction is BCD/Hex, Decimal and Binary.
