Word AND

The AND function compares each bit in the first specified register against each corresponding bit in the second specified register. If both bits are 1, it places a 1 in the corresponding bit of the third register. If either or both of the corresponding bits is 0, the AND function places a 0 in the corresponding location in the third register.
