Description

Performs a bitwise AND operation between A and the byte whose address is:

• the sum of IX and the 8-bit signed displacement d, or

• the sum of IY and the 8-bit signed displacement d

The result is stored in A.

The Rabbit 4000/5000 assemblers view "AND A,(IX+d)" and "AND (IX+d)" as equivalent instructions. The same is true for "AND A,(IY+d)" and "AND (IY+d)."

Example

If the byte in A contains the value 1011 1100 and the byte at memory location IX+d contains the value 1101 0101, then the execution of the instruction:

AND (IX+d)

would result in the byte in A becoming 1001 0100.
