Abstract: A transceiver includes a frequency modulation continuous wave generator to generate a frequency sequence and a digital phase locked loop to generate a waveform based on the frequency sequence. The digital phase locked loop includes a plurality of control registers. A main controller captures a reference state defined in the plurality of configuration registers prior to the frequency sequence, initiates the frequency sequence, restores the reference state of the configuration registers after completion of the frequency sequence, and repeats the frequency sequence after restoring the reference state.
