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