AND With Accumulator
AND
7-35
Assembly Language Instructions
Status Bits None
This instruction is not affected by SXM.
Description If direct or indirect addressing is used, the low word of the accumulator is
ANDed with a data-memory value, and the result is placed in the low word posi-
tion in the accumulator. The high word of the accumulator is zeroed. If immedi-
ate addressing is used, the long-immediate constant can be shifted. During the
shift, low-order and high-order bits not filled by the shifted value are zeroed.
The resulting value is ANDed with the accumulator contents.
