Revision 7_8, October 10
For each CAP pin a threshold level can be set individually.
The threshold levels are used by the SX8635 for making touch and release decisions on e.g. touch or no-
touch.
The details are explained in the sections for buttons and wheel.
The SX8635 offers a periodic offset compensation for applications which are subject to substantial
environmental changes. The periodic offset compensation is done at a defined interval and only if wheel and
buttons are released.
