PRODUCTION DATA
A logic 1 on NVM-CRC-FAIL-INT bit indicates that the internal NVM data are corrupt. During this condition, all registers in the DAC are initialized with factory reset values, and all DAC registers can be written to or read from. In case of a temporary failure, to reset the alarm bits to 0, issue a software reset command (see Section 7.4.3.2) or cycle power to the DAC. A permanent failure in the NVM makes the device unusable.
