Abstract
An example system comprises first circuitry (such as a first integrated circuit device having a limited number of input/output pins) and second circuitry (such as a second integrated circuit device having a limited number of input output pins). The second circuitry is communicatively coupled to receive communications over a communication link from the first circuitry. In one embodiment, the first circuitry includes a monitor circuit. The monitor circuit monitors a voltage rail inputted to power the first circuitry. The monitor circuit initiates switching between transmitting a control signal (such as status information indicating whether the first circuitry is powered correctly) and a data signal over a communication link from the first circuitry to second circuitry depending upon the magnitude of the voltage rail. For example, when the first circuit is properly powered, the monitor circuit initiates transmission of the data signal over the communication link to the second circuitry.
