Explanation
1. This instruction applies the logical operator AND to the binary representations in S
AND operation on each pair of corresponding bits and stores the result in D.
2. Only the DAND instruction can use the 32-bit counter.
3. The result in each position is 1 if the first bit is 1 and the second bit is 1; otherwise, the result is 0.
Example 1
When X0.0 is ON, the instruction performs the logical operation AND on each pair of corresponding bits in the 16-bit
device Y0 and the 16-bit device Y2. It stores the result in Y4.
