Abstract: This relates to interface circuits for synchronous protocols which do not rely on a dedicated high frequency clock signal. Instead, the interface circuit may rely on a clock signal received over the interface from another device in order to transfer data between the interface and an internal buffer. Furthermore, the interface circuits can rely on a clock signal provided by a bus for a device the interface circuit is located in to transfer data between the internal buffer and the bus. The internal buffer can be, but is not limited to a FIFO. Alternatively, it can be a stack or another data structure. The internal buffer can be configured so that each of its multiple of cells is a shift register. Thus, a preparatory step of moving a byte of data from the buffer to a separate shift register can be avoided.

Abstract: A device that can autonomously scan a sensor panel is disclosed. Autonomous scanning can be performed by implementing channel scan logic. In one embodiment, channel scan logic carries out many of the functions that a processor would normally undertake, including generating timing sequences and obtaining result data; comparing scan result data against a threshold value (e.g., in an auto-scan mode); generating row count; selecting one or more scanning frequency bands; power management control; and performing an auto-scan routine in a low power mode.

Abstract: A system and method for autonomously scanning a sensor panel device is disclosed. A sensor panel processor can be disabled after a first predetermined amount of time has elapsed without the sensor panel device sensing any events. One or more system clocks can also be disabled to conserve power. While the processor and one or more system clocks are disabled, the sensor panel device can periodically autonomously scan the sensor panel for touch activity. If one or more results from the autonomous scans exceed a threshold, the sensor panel device re-enables the processor and one or more clocks to actively scan the sensor panel. If the threshold is not exceeded, the sensor panel device continues to periodically autonomously scan the sensor panel without intervention from the processor. The sensor panel device can periodically perform calibration functions to account for any drift that may be present in the system.

Abstract: A channel scan architecture for detecting touch events on a touch sensor panel is disclosed. The channel scan architecture can combine drive logic, sense channels and channel scan logic on a single monolithic chip. The channel scan logic can be configured to implement a sequence of scanning processes in a panel subsystem without intervention from a panel processor. The channel scan architecture can provide scan sequence control to enable the panel processor to control the sequence in which individual scans are implemented in the panel subsystem.

Abstract: Embodiments of the present invention are directed to a microcontroller which includes a Register Load Assist engine. The microcontroller can include no or minimal non-volatile memory which stores boot data. Thus, most of the boot data can be stored at a non-volatile memory external to the microcontroller. An external circuit can read the externally positioned non-volatile memory and send compressed boot data to the microcontroller. The boot data can be originally stored in compressed form in the external non-volatile memory or it can be compressed by the external circuit. The boot data can be received by the microcontroller and saved in an intermediate location in the microcontroller's internal volatile memory. The RLA engine can then uncompress the boot data and store various portions of it in their final destinations (such as, for example, in respective registers).

Abstract: An oscillating signal of relatively precise frequency is generated by tuning an oscillator using an external stable oscillating source as a reference. Calibration logic is included to compare a signal from the local oscillator to the reference signal and vary the local signal to a desired frequency. In one embodiment, a binary search algorithm is used to tune the local oscillator. The local oscillating signal can be sent to one or more circuits including at least one sensor of a touch sensitive panel for detecting touch events.

Abstract: A power management system for a touch controller can include a transmit section for transmitting stimulation signals to an associated touch sensor panel to drive the panel, where the touch controller can selectively adjust the transmit section to reduce power during the transmission. The touch controller can also include a receive section for receiving touch signals resulting from the driving of the panel, where the touch controller can selectively adjust the receive section to reduce power during the receipt of the touch signals. The touch controller can also include a demodulation section for demodulating the received touch signals to obtain touch event results, where the touch controller can selectively adjust the demodulation section to reduce power during the demodulation of the touch signals. The touch controller can also selectively reduce power below present low levels during idle periods. The touch controller can be incorporated into a touch sensitive device.

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.
