And Formatted (ANDF)
The And Formatted instruction logically ANDs the binary value in
the accumulator and a specified range of discrete memory bits (1 to
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).
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.
Discrete Bit Flags Description
SP63 Will be on if the result in the accumulator is zero
SP70 Will be on if the result in the accumulator is negative
