Overview
When driving conditions are met, the WAND instruction performs a logical AND on S1 and S2 bit by bit. The
result is stored in D.

Function
The bit patterns of the BIN values in S1 and S2 are analyzed. The result of the logical AND analysis is
stored in the variable D.
The result of a logical AND operation is 0 if the value of either S1 or S2 is 0.
1•1 = 1 1•0 = 0 0•1 = 0 0•0 = 0
