Claim 15:
16. A mobile industry processor interface (MIPI) core comprising a processor configured to:
detect an address voltage at a configuration terminal of a MIPI radio frequency front end (RFFL) device, further comprising:
detecting both an increasing slope and a first minimum voltage of a supply voltage to the MIPI RFFE device to determine a start time of a sense period;
determining a stop time of the sense period at an n-th clock of a MIPI RFFE clock signal that begins after the start time, where n is smaller than a minimum length of the MIPI RFFE clock signal such that the stop time occurs while the MIPI RFFE clock signal is active;
measuring the address voltage at the stop time; and
determining an MIPI RFFE address of an MIPI RFFE device based on the address voltage measured.
