Bit String Processing Instructions
2
AND (&), OR, and XOR
These instructions perform processing on Boolean variables or corresponding bits in bit strings. The
data to process is in In1 to InN. In1 to InN and Out must be the same data types.
If there are more than two data to process, processing is performed with the following procedure.
1
Processing is performed for In1 and In2.
2
Processing is performed for the results of step 1 and In3.
3
Processing is performed for the results of step 2 and In4.
The relationships between input and output variables are given in the following tables.
z AND (&)
If both bits are TRUE, then the processing result is TRUE. Otherwise, the processing result is FALSE.
z OR
If both bits are FALSE, then the processing result is FALSE. Otherwise, the processing result is TRUE.
z XOR
If both bits are the same, then the processing result is FALSE. If one bit is TRUE and the other is
FALSE, then the processing result is TRUE.
