To take measurements with the touch screen controller, the ADC has to be enabled and configured for use with the touch screen controller (TSC) first. In case the TSC is planned to be operated interrupt driven, the TSC needs to be in TSC standby mode per default. Only in TSC standby mode an interrupt is generated based on a touch of the screen. The TSC should therefore be in this mode until a touch is detected. Afterwards, the TSC has to be configured for x-position measurement followed by y-position measurement. Now, the TSC can be set to TSC standby again to wait for the next touch of the screen. For a non-interrupt driven sequence, see TSCMODE. Register Address: 08h (page 50) in the Registers section. A typical interrupt driven sequence is given below:
