Explanation:
1. The logical operator XOR takes the binary representations in S
logical exclusive OR operation on each pair of corresponding bits. The operation result is
stored in D.
2. Only the instruction DXOR can use the 32-bit counter.
3. The result in each position is 1 if the two bits are different, and 0 if they are the same.
Example 1:
When X0.0 is ON, the logical operator XOR takes the data in the 16-bit device Y0 and the 16-bit
device Y2, and performs the exclusive OR operation on each pair of corresponding bits. The
operation result is stored in Y4.
