6.3.8.3
The clock for the CAT module, CLK_CAT, is generated by the Power Manager (PM). This clock is
turned on by default, and can be enabled and disabled in the PM. The user must ensure that
CLK_CAT is enabled before initializing the QTouch Library.
The QTouch method acquisition using the CAT module requires one Peripheral DMA channel
that must be provided by the application.
