The prescaler is used to ensure that the CLK_CAT clock is divided to around 4 MHz to produce the burst timing clock.The
prescaler uses the following formula to generate the burst timing clock:
Burst timing clock = CLK_CAT / (2(DIV+1))
For QMatrix sensors, specifies how many burst prescaler clock cycles should be used for transferring charge to the sense
capacitor.
For QMatrix sensors, specifies how many burst prescaler clock cycles should be used for settling after charge transfer.
