Description

Data type of result

(S1)

(S2)

Data which will be EXCLUSIVE ORed bit-by-bit

Data type of (S1) or (S2)

which is greater

(Integer type)

[Functions]

(1) The bit-by-bit exclusive logical add of the data specified with (S1) and the data

specified with (S2) is found.

(2) When (S1) and (S2) differ in data type, the data of the smaller data type is

converted into that of the greater type before operation is performed. At this time,
note that signed data is converted.

[Errors]

(1) An operation error will occur if:

• (S1) or (S2) is an indirectly specified device and its device No. is outside the

range.

[Program examples]

(1) Program which EXCLUSIVE ORs #0 and #1 and substitutes the result to D0

D0 = #0 ^ #1
