The ZL30117 is mainly controlled by accessing software registers through the serial peripheral interface (SPI). The
device can be configured to operate in a highly automated manner which minimizes its interaction with the system’s
processor, or it can operate in a manual mode where the system processor controls most of the operation of the
device.
The following table provides a summary of the registers available for status updates and configuration of the device.
