@654 <Var> <Var 1> <Value>
The bit pattern in <Value> is logically negated. The result is stored in <Var>.
Example:
R50 = 00101100
@654 R52 R50
@655 <Var> <Var 1> <Value>
Bit 0 in <Var 1> and <Value > is logically ORed. The result is stored in <Var>.
@656 <Var> <Var 1> <Value>
Bit 0 in <Var 1> and <Value > is logically EXORed. The result is stored in <Var>.
@657 <Var> <Var 1> <Value>
Bit 0 in <Var 1> and <Value > is logically ANDed. The result is stored in <Var>.
Example:
R50 = 1
R51 = 0
@657 R52 R50
@658 <Var > <Var 1> <Value>
Bit 0 in <Var 1> and <Value > is logically ANDed. The result is negated and stored in
<Var>.
Example:
R50 = 1
R51 = 0
@658 R52 R50
@659 <Var> <Value>
The logic value (0 or 1) in <Value> is negated. The result is stored in <Var>.
