Table 7-36 GENERAL-STATUS Register Field Descriptions
Bit Field Type Reset Description
15 NVM-CRC-FAIL-INT R 0 0: No CRC error in OTP
1: Indicates a failure in OTP loading. A software reset or power-cycle can bring the device out of this condition in case of temporary failure.
14 NVM-CRC-FAIL-USER R 0 0: No CRC error in NVM loading
1: Indicates a failure in NVM loading. The register settings are corrupted. The device allows all operations during this error condition. Reprogram the NVM to get original state. A software reset brings the device out of this temporary error condition.
