And Formatted (ANDF)
The And Formatted instruction logically ANDs the binary value in
230
the accumulator and a specified range of discrete memory bits (1 to
240
32). The instruction requires a starting location (Aaaa) and number
250-1
of bits (Kbbb) to be ANDed. Discrete status flags indicate if the
260
result is zero or a negative number (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 accumulator contents is logically ANDed with the
bit pattern from Y20–Y23 using the And Formatted instruction. The Out Formatted
instruction outputs the accumulator's lower four bits to C20–C23.
