Abstract
A touch display driving circuit capable of responding to CPU commands, including: a first interface receiving touch configuration data from a CPU and outputting touch report data to the CPU; a second interface coupling with a touch display module; a control unit executing a touch detection procedure on the touch display module via the second interface to derive touch detected data, and processing the touch detected data to generate the touch report data, wherein the touch detection procedure is determined according to the touch configuration data determining a connection configuration of at least one multiplexer and a weighting configuration of at least one touch point, and the content of the touch report data include a sensed pressure profile, a finger print, a palm print, an ear image, characteristics of a finger print, characteristics of a palm print, or characteristics of an ear image.
