Description:
The result of a bitwise logical AND of the source operand and the destination operand is
used to set or clear the Z flag accordingly; the result itself is not retained.
All operands and the result are interpreted as bit-string of 32 bits each.
Operation:
Z := (Rd and Rs) = 0;
Exceptions:
None
