AND
Operation:
Description:
Example:


dst,src
A,#im
A,@HL
EA,RR
RRb,EA
The source operand is logically ANDed with the destination operand. The result is stored in the
destination. The logical AND operation results in a "1" whenever the corresponding bits in the two
operands are both "1"; otherwise a "0" is stored in the corresponding destination bit. The contents
of the source are unaffected.
A,#im
A,@HL
EA,RR
RRb,EA
If the extended accumulator contains the value 0C3H (11000011B) and register pair HL the value
55H (01010101B), the instruction
AND
leaves the value 41H (01000001B) in the extended accumulator EA .
