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 ORF instruction logically ORs the accumulator contents with Y20–
Y23 bit pattern. The ORF instruction outputs the accumulator’s lower four bits to C20–C23.

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