XOR
— Logical Exclusive OR
XOR dst,src
Operation: Operand
A,#im
A,@HL
EA,RR
RRb,EA
Description: XOR performs a bitwise logical XOR operation between the source and destination variables and
stores the result in the destination. The source contents are unaffected.
Operand
A,#im
A,@HL
EA,RR
RRb,EA
Example: If the extended accumulator contains 0C3H (11000011B) and register pair HL contains 55H
(01010101B), the instruction
XOR
leaves the value 96H (10010110B) in the extended accumulator.
Exclusive-OR immediate data to A
