The touch screen on the TS-TPC-8390 is comprised of a two channel ADC and a portion of the TS-47XX's FPGA. The touch controller's raw data can be accessed for a number of custom applications, including the collection of custom calibration data and polling for specific touch instances. This data is presented with two registers on the TS-47XX:

Address Bit range Function
0x80005000 15:1 X touch position value
0x80005000 0 Touch Flag (1=touch)
0x80005002 15:1 Y touch position value
0x80005002 0 Touch Flag (1=touch)
