Abstract
A method performed by a system is provided, wherein the system includes a touch IC executing touch detection and an external processor, which is different from the touch IC and which may include a touch IC support firmware. The system includes a sensor electrode group connected to the touch IC; and a first bus connecting the touch IC with the external processor. The touch IC generates frame data indicative of a detection level of each of two-dimensional positions in the sensor electrode group, and supplies the frame data to the external processor via the first bus. The external processor feeds determination data resulting from performing predetermined processing on the frame data back to the touch IC, and the touch IC performs an operation based on the determination data. Thus, the touch IC can utilize the processing results of the external processor.
