
A logical OR operator takes the binary representations in S
1
and S
2
, and
performs the logical inclusive OR operation on each pair of
corresponding bits. The operation result is stored in
D .

S
1
: Source device 1; S
2
: Source device 2; D : Operation result

The result in each position is 1 if the first bit is 1, the second bit is 1, or
both bits are 1. Otherwise, the result is 0.


When X0.0 is ON, a logical OR operator takes the values in the 16-bit
device D0 and the 16-bit device D2, and performs the logical inclusive
OR operation on each pair of corresponding bits, and the operation
result is stored in D4.

When X0.1 is ON, a logical OR operator takes the values in the 32-bit
device (D11, D10) and the 32-bit device (D21, D20), and performs the
logical inclusive OR operation on each pair of corresponding bits, and
the operation result is stored in (D41, D40).
