ABSTRACT:
A method for resetting a key decoder coupled to a plurality of capacitive keys to prevent processing of a key code generated by a ghosting condition. The method includes receiving a key code from a key decoder that corresponds to a first capacitive key of a capacitive keypad, detecting a ghosting condition for a second capacitive key that does not correspond to the detected key code, and resetting a key decoder in response to the ghosting condition being detected.
