Abstract:
Activation of an external sensor coupled to an electronic device will change the frequency of a low power oscillator in the electronic device that runs during a low power sleep mode of the electronic device. When a change in frequency of the low power oscillator is detected, the electronic device will wake-up from the low power sleep mode. In addition, when a change in frequency from an external frequency source is detected, the electronic device will wake-up from the low power sleep mode.
