Compare Formatted (CMPF)
The Compare Formatted 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.
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.
