2 Instruction Descriptions

AND and ANDN

AND: Takes the logical AND of the value of a BOOL variable and the execution condition.
ANDN: Takes the logical AND of the inverse of the value of a BOOL variable and the execution
condition.
Instruction Name
AND AND
ANDN AND NOT
Variables
None
Function
 AND
The AND instruction takes the logical AND of the value of a specified BOOL variable and the execution
condition and outputs it to the next instruction. Use the AND instruction for a NO bit connected in series
with the previous instruction.
 ANDN
The ANDN instruction takes the logical AND of the inverse of the value of a specified BOOL variable
and the execution condition and outputs it to the next instruction. Use the ANDN instruction for a NC bit
connected in series with the previous instruction.
The following figure shows a programming example of the AND instruction. It takes the logical AND of
variable A and variable B and outputs it to variable C.
