Removing Wires

The tampering action like missing neutral and missing Potential are caused because of the phase or neutral wire removal. There will be Analog frontend units which tracks the phase and neutral signals continuously. When someone is attempting to remove the phase or neutral line, the Analog Frontend will trigger an interrupt to the microcontroller connected to it. If the Analog frontend module triggers a rising/falling edge on the RTC/IN pin of SAM L22, the tamper condition will be detected.
