Bit exclusive logical OR: ^
■Usable data
: Usable
■Description, data type of result
• The bit-by-bit exclusive logical add of the data specified with (S1) and the data specified with (S2) is found.
• 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.
An operation error will occur if:
• (S1) or (S2) is an indirectly specified device and its device No. is outside the range.
■Program which EXCLUSIVE ORs #0 and #1 and substitutes the result to D0
