Explanation
A logical OR operator takes the bina
ry 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.
Example 1
When X0 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.

Example 2
When X1 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).
