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.
