Operands:
S 1 : Source device 1 S 2 : Bits to be masked (OFF) D: D =( S 1 & S 2 ) | ( D & ~ S 2 )
Explanations:
1. The instruction conducts logical AND operation between S 1 and S 2 first, logical AND operation
between D and ~S 2 secondly, and combines the 1 st and 2 nd results in D by logical OR
operation.
2. Rule of Logical AND operation: 0 AND 1 = 0, 1 AND 0 = 0, 0 AND 0 = 0, 1 AND 1 = 1
3. Rule of Logical OR operation: 0 OR 1= 1, 1 OR 0 = 1, 0 OR 0 = 0, 1 OR 1 = 1.
Program Example 1 :
When X0 = ON, MVM instruction conducts logical AND operation between 16-bit register D0 and
H’FF00 first, logical AND operation between D4 and H’00FF secondly, and combines the 1 st and 2 nd
results in D4 by logical OR operation.
