Explanation:
1. The logical operator OR 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.
2. Only the instruction DOR can use the 32-bit counter.
3. 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 X0.0 is ON, the logical operator OR takes the data in the 16-bit device Y0 and the 16-bit
device Y2, and performs the logical inclusive OR operation on each pair of corresponding bits. The
operation result is stored in Y4.
