Note:

The XPL_NRST signal must be connected to a GPIO in the host controller with an internal pull-down default reset configuration.
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.
See 3.3.4 Zero-Crossing Detector Circuit for more information.
