Abstract: In one embodiment, a method includes: powering on an integrated circuit (IC) and causing the IC to enter into a reset mode, where in the reset mode, a switch coupled between an oscillator of the IC and a reset pin is open; releasing the reset pin to cause the IC to enter into a non-reset mode, where in the non-reset mode the switch is closed to cause the clock signal to be superimposed on a reset signal at the reset pin; and determining, via a monitoring circuit coupled to the IC, the IC as functional in response to identifying the clock signal superimposed on the reset signal at the reset pin.

Abstract: In one embodiment, an apparatus includes: an oscillator to output a clock signal on a first line; a switch coupled to the first line; and a voltage divider coupled to the switch. The switch may be controlled to output the clock signal through the voltage divider via the first line to a pin in a non-reset mode and prevent the clock signal from being provided to the pin in a reset mode.
