There are two system registers that provide this touch feature:
%SR9 (I/O Name - TCH_PRESSURE)
Records the highest pressure level of the last touch on the screen that exceeds the threshold
value set in %SR10. This is a range of 0 to 3000. Zero (0) indicates no pressure and 3000 is the
maximum amount of pressure that can be measured.
%SR10 (I/O Name - TCH_PRESSURE_TSH)
This register sets the pressure threshold to indicate a touch. A value of 200 is typically the
lightest touch, 600 is moderate and 1000+ is a heavy touch.
These new features allow customizing the feel of the touch screen and can be used to add unique user
interface features such as having different operations depending on the force of the touch.
