For the autonomous QTouch sensor and DMATouch sensors, specifies how many bits the DILEN field should be shifted before
using it to determine the discharge time.
For the autonomous QTouch sensor and DMATouch sensors, specifies that acquisition shall begin when a falling edge is
received on the SYNC line.
For the autonomous QTouch sensor and DMATouch sensors, specifies that spread spectrum sensor drive shall be used.
For the autonomous QTouch sensor and DMATouch sensors, specifies how many sample clock cycles the CAT should use to
discharge the capacitors before charging them.
For the autonomous QTouch sensor and DMATouch sensors, specifies how many counts the maximum acquisition should be.
