In option A, Resistive drive is enabled on SNSK line. In case B,Resistive drive is disabled on the SNSK line and in this case, it is recommended to use 1kOhmresistors on SNSK Line external to the UC3L device.SYNC pin optionIn order to prevent interference from the 50 or 60 Hz mains line the CAT can optionally triggerQTouch Group A/B and Autonomous QTouch acquisition on the external SYNC input signal. TheSYNC signal should be derived from the mains line and the acquisition will trigger on a falling1268207K-AT42-09/11

This clock isturned on by default, and can be enabled and disabled in the PM. The user must ensure thatCLK_CAT is enabled before initializing the QTouch Library.127
