Abstract: Touch sensing can be accomplished using master/slave touch controllers that transmit drive signals to a touch surface and process sense signals including superpositions resulting from master/slave drive signals. The master/slave can drive and sense different sets of lines, respectively, of the touch surface. A communication link between master/slave can be established by transmitting a clock signal between master/slave, transmitting a command including sequence information to the slave, and initiating a communication sequence from the clock signal and sequence information. The slave can receive/transmit communications from/to the master during first/second portions of the communication sequence, respectively. Touch sensing operations can be synchronized between master/slave by transmitting a command including phase alignment information from master to slave, and generating slave clock signals based on the clock signal and the phase alignment information, such that sense signal processing by master clock signals are in-phase with sense signal processing by slave clock signals.

Abstract: A method and system for managing power in a computer system is disclosed. In one embodiment the method includes providing output signals from a sensor panel to a controller, wherein the controller includes a data bus and a plurality of devices communicatively coupled to the data bus; monitoring an activity level on the data bus by monitoring bus access requests by one or more of the plurality of devices; and reducing or shutting off a bus clock frequency if there is reduced or no activity on the bus for a predetermined period of time.
