PRODUCTION DATA.
The device has four 8-bit configuration registers that are accessible through the serial interface using the RREG and WREG commands. The configuration registers control how the device operates and can be changed at any time without causing data corruption. After power-up or reset, all registers are set to the default values (which are all 0). All registers retain their values during power-down mode. Table 11 shows the register map of the configuration registers.
