PRODUCTION DATA.
The device control registers can be accessed using either I2C or SPI communication to the device.
By monitoring the SDA_SSZ, SCL_MOSI, ADDR0_SCLK, and ADDR1_MISO device pins, which are the multiplexed pins for the I2C or SPI Interface, the device automatically detects whether the host device is using I2C or SPI communication to configure the device. For a given end application, the host device must always use either the I2C or SPI interface, but not both, to configure the device.
