   Note:

   1. The XPL_NRST signal must be connected to a GPIO in the host controller with an internal pull-down default reset configuration.
   2. The XPL_STBY signal must be connected to GND when not using the Sleep mode functionality. When using it, the XPL_STBY signal must be connected to a GPIO in the host controller with an internal pull-down default reset configuration.
   3. See Zero-Crossing Detector Circuit for more information.
