Switch
This function block switches between two given input signals.
The binary signal SEL controls the switch. If SEL is LOW, the input value INP1 is selected for the output OUT. If SEL is HIGH, the input value INP2 is selected for the output OUT.
Operation
SEL = LOW -> OUT = INP1
SEL = HIGH > OUT = INP2
