/// \unit
///
/// !!!Purpose
///
/// This unit provides a very powerful touchscreen driver which handles all the
/// complexity. This includes touchscreen calibration, retrieving measurements,
/// configuring the TSADC, etc.
///
/// !!!Usage
///
/// -# Call TSD_Initialize() whenever the touchscreen should start the
/// calibration process (as it is done in the function).
/// -# Declare a global TSD_PenPressed function anywhere in your code. This
/// function will get called every time the pen is pressed on the screen.
/// -# Declare a global TSD_PenMoved function, which will get called whenever
/// the pen stays in contact with the screen but changes position.
/// -# Declare a global TSD_PenReleased function, which will be invoked as the
/// pen is lifted from the screen.
