(1) Cyclic sensing for WAKE1, WAKE2 and WAKE3 pin uses a low power 10kHz internal clock to reduce the current consumption. Cyclic sensing for WAKE4 pin uses the 1MHz internal clock that consumes more current than the 10kHz clock. It is recommended to use WAKE1-3 pins for cyclic sensing for lower current consumption.
