DXOR
(1) Conducts an exclusive OR operation on each bit of the 32-bit data of the device designated
by and the 32-bit data of the device designated by , and stores the results at the device
designated by .
(2) For bit devices, the bit devices after the points designated by digit specification are regarded
as "0" in the operation.
Operation Error
(1) There are no operation errors associated with the WXOR(P) or DXOR(P) instructions.
Program Example
