Explanation:
1. The logical operator XNR takes the binary representations in S
logical exclusive NOR operation on each pair of corresponding bits. The operation result is
stored in D.
2. Only the instruction DXNR can use the 32-bit counter.
3. The result in each position is 1 if the two bits are the same, and 0 if they are different.
Example 1:
When X0.0 is ON, the logical operator XNR takes the data in the 16-bit device Y0 and the 16-bit
device Y2, and performs the logical exclusive NOR operation on each pair of corresponding bits.
The operation result is stored in Y4.
Example 2:
When X0.0 is ON, the logical operator XNR takes the data in the 32-bit device (Y11, Y10) and the
32-bit device (Y21, Y20), and performs the logical exclusive NOR operation on each pair of
corresponding bits. The operation result is stored in (Y41, Y40).
