10.10 Error Conditions
The prefetch module handles and reports information about two error types:
- ECC Double-bit Error Detected (DED)
- ECC Single-bit Error Corrected (SEC)
The user can enable and disable the ECC Error detection logic using the configuration bits, ECCCTL[1:0] (CFGCON0/DEVCFG0[29:28]).
The ECC logic increases the read access delay from the PFM. Depending on the frequency of the system clock, the Wait states can be different between ECC-enabled and ECC-disabled.
Note: ECC errors are captured for predictive prefetch
reads of the PFM. However, do not report those
errors until, and unless, the system starts using
that data.
