Abstract:
A system and method for enabling noise avoidance between multiple capacitive touch sensing circuits operating in a same device and which may interfere with each other, wherein a master controller is coupled to all of the capacitive touch sensing circuits to prevent them from using measurement frequencies and from jumping to new measurement frequencies that may interfere with each other, thereby allowing the capacitive touch sensing circuits to function properly.
