3.4.3.3.3 Corrected Program Memory Data Errors
The program memory error correction logic may correct a data error in the program data supplied to the PBU. These corrections are not reported to the PBU which is usually done for the uncorrectable errors. Specifically, a single-bit corrected error (SEC event) is not reported to the PBU.
The program memory is responsible for tracking and reporting the corrected event. These actions serve as a warning to the system software that integrity of the NVM data may be failing.
