Abstract
A power detection and indication circuit device includes a processor, a signal conditioning circuit coupled to the processor and an indicator coupled to the signal conditioning circuit. The power detection and indication circuit performs a test to determine the presence of a switch coupled to the processor through the conditioning circuit. In response to determining that the switch is coupled to the processor through the conditioning circuit, the power detection and indication circuit performs a test to determine a status of the switch and provides an indication of the status of the switch using the indicator.
