ABSTRACT:
A system for monitoring interrupts to a processor includes a multiplexer having a plurality of inputs connected to receive various analog inputs. The multiplexer further has an output which is programmably connected to one of the plurality of inputs responsive to a control signal. An analog to digital converter is connected to the output of the multiplexer for converting an analog signal at the output to a digital signal. An auto-scan block generates the control signal provided to the multiplexer. The control signal selects ones of the plurality of inputs of the multiplexer for connection to the output in a programmably defined order.
