NOTE: Status flags are valid only until another instruction uses the same flag.
In the following example, when X1 is on, the LDF instruction loads C10–C13 (4 binary bits)
into the accumulator. The accumulator contents is logically ANDed with the bit pattern from
Y20–Y23 using the ANDF instruction. The OUTF instruction outputs the accumulator’s
lower four bits to C20–C23.

And Formatted (ANDF)
The ANDF instruction logically ANDs the binary value in
the accumulator with a specified range of discrete memory
bits (1–32). The instruction requires a starting location
(Aaaa) and number of bits (Kbbb) to be ANDed. Discrete
status flags indicate if the result is zero or a negative number
(the most significant bit =1).
