Or Formatted (ORF)
The Or Formatted instruction logically ORs the binary value
in the accumulator and a specified range of discrete bits (1 to
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).
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 C10–C13
(4 binary bits) into the accumulator. The Or Formatted instruction logically ORs the
accumulator contents with Y20–Y23 bit pattern. The Out Formatted instruction outputs the
accumulator’s lower four bits to C20–C23.
