摘要： An integrated circuit comprises a host interface control block for providing a connection between the integrated circuit and a master controller device. The integrated circuit further includes a plurality of I/O pins. A capacitive touch sense circuitry enables detection of actuation of at least one capacitor switch of a capacitive sensor array connected to at least a portion of the plurality of I/O pins. An LCD controller drives at least one LCD connected to at least a portion of the plurality of I/O pins. The integrated circuit, responsive to signals received from the master controller device over the host interface control block, may be configured to monitor outputs from the capacitive sensor array in a first mode of operation. In a second mode of operation, the capacitive sensor array may be configured to drive at least one LCD. Finally, in a third mode of operation, the integrated circuit may be configured to both monitor outputs of the capacitive sensor array and drive the at least one LCD.
