1. Control circuitry configured to be coupled to a wireless power transfer coil of an electronic device, the control circuitry being further configured to:
initiate a frequency-shift keying communication during which wireless power signals provided to the wireless power transfer coil are modulated between a first frequency and a second frequency that is different than the first frequency;
while transmitting modulation states for the frequency-shift keying communication, determine if amplitude-shift keying modulation of the wireless power signals is present; and
in response to determining the amplitude-shift keying modulation of the wireless power signals is present, abort the frequency-shift keying communication.
