256
XORX
Definition
Logical Exclusive OR using Extended Addressing.
Syntax
XORX dst, src
Operation
dst
 dst XOR src
Description
For this new eZ8 extended addressing instruction, the source operand is
logically EXCLUSIVE ORed with the destination operand. An XORX
operation stores a 1 in the destination operand when the corresponding
bits in the two operands are different; otherwise it stores a 0. The contents
of the source operand are unaffected.
Flags
C Unaffected
Z Set if the result is zero; reset otherwise
S Set if Bit 7 of the result is set; reset otherwise
V Reset to 0
D Unaffected
H Unaffected
