9.9 Error Conditions

The Prefetch module handles and reports information about two error types: ECC Double-bit Error Detected (DED) and ECC Single-bit Error Corrected (SEC). The ECC Error detection logic is enabled and disabled 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 may be different between ECC-enabled and ECC-disabled.

Note: ECC errors are captured for predictive prefetch reads of the PFM. However, those errors are not reported until, and unless, that data is used by the system.
