Logical Exclusive OR
XOR op1, op2
(op1) ← (op1) ⊕ (op2)
WORD
Performs a bitwise logical EXCLUSIVE OR of the source operand speci-
fied by op2 and the destination operand specified by op1. The result is
then stored in op1.
E Z
* *
E Set if the value of op2 represents the lowest possible negative number.
Cleared otherwise. Used to signal the end of a table.
Z Set if result equals zero. Cleared otherwise.
V Always cleared.
C Always cleared.
N Set if the most significant bit of the result is set. Cleared otherwise.
