XOR
Operation:
Description:
Example:

dst,src
A,#im
A,@HL
EA,RR
RRb,EA
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.
A,#im
A,@HL
EA,RR
RRb,EA
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.
