XOR (EXCLUSIVE OR)
This function exclusively logically ORs the connected input signals. The connected input signals must be digital input signals.
Logic EXCLUSIVE ORing is carried out as follows:
If both INPUTS are at the same level (both set to ON or both set to OFF), the OUTPUT is set to OFF. If one of the inputs is set to ON and the other is set to OFF, the output is set to ON.
The non-connected input or inputs are set to ON.
