The prescaler is used to ensure that the CLK_CAT clock is divided to around 1 MHz to produce the sampling clock.The
prescaler uses the following formula to generate the sampling clock:
Sampling clock = CLK_CAT / (2(DIV+1))
For the autonomous QTouch sensor, specifies how many sample clock cycles should be used for transferring charge to the
sense capacitor.
For the autonomous QTouch sensor, specifies how many sample clock cycles should be used for settling after charge transfer.
