PRODUCTION DATA
The device is primarily configured and controlled using the serial programming interface (SPI). However, it can operate in a default configuration without requiring the SPI interface. Furthermore, the power down function as well as internal and external reference configuration is possible via pin control (PDN/SYNC and REFBUF pin).
After initial power up, the default operating configuration for each device is shown in Table 8-11.
