摘要： An LCD controller includes at least one I/O pad for providing an LCD drive voltage in an LCD mode of operation. I/O pad logic drives the at least one I/O pad responsive to a provided bias voltage. Voltage selection logic selects a higher voltage between an LCD drive voltage and an externally provided system voltage as a first voltage. Bias voltage logic selects one of the system voltage or the first voltage as the bias voltage for the I/O pad logic. The system voltage is selected as the bias voltage for the I/O pad logic in a non-LCD mode of operation for the I/O pad and the first voltage is selected for the bias voltage for the I/O pad logic in the LCD mode of operation for the I/O pad.

摘要： A system and method for an anti-pinch powered window system includes a window and a mechanical drive mechanism for raising and lowering the window. An electric motor drives the mechanical drive mechanism responsive to a command. A microcontroller unit generates the command responsive to a measured load current of the electric motor. A command to change direction of the window is generated responsive to a determination that the measured load current has exceeded a variable threshold level indicating that the window has stopped due to an obstruction. The variable threshold level is determined by the load current data stored within a memory.

摘要： The integrated system on a chip with LINBUS network communication capabilities includes processing circuitry for performing predefined digital processing functionalities on the chip. A free running clock circuit generates a temperature compensated clock that does not require a synch signal from external to the chip. A LINBUS network communications interface digitally communicates with off-chip LINBUS devices. Communication between said on-chip LINBUS communications interface and the off-chip LINBUS devices is affected without clock recovery. The LINBUS network communication interface has a time base derived from the temperature compensated clock which is independent of any timing information in the input data received during a receive operation. The temperature compensated clock further provides an on-chip time reference for both the processing circuitry and the LINBUS network communications interface.

摘要： The method is described for selecting capacitors from a capacitor array for each bit of a SAR ADC. The process involves selecting a group of capacitors from the capacitor array and determining a weight of the selected group of capacitors. A determination is made if the weights of the selected group of capacitors are substantially equal to their desired values. If the weights are substantially equal to their desired values, the selected group of capacitors is associated with each bit of the SAR ADC. If the weights are not substantially equal to their desired values, a next group of capacitors from the capacitor array is selected for the bits. This process of selecting a group of capacitors and determining their weights is repeated until determined weight for a group of capacitors equals or is closest to the desired values.
