4. Notify the local MPU via interrupt if so enabled.
Triple (or Greater) Bit Error (Cycle Type = Non-Burst Write)
Some of these errors are detected correctly and are handled the same as a
double-bit error. The rest may show up as "no error" or "single-bit error",
both of which are incorrect.
Single Bit Error (Cycle Type = Scrub)
1. Write corrected data to the DRAM.
2. Log the error if not already logged.
3. Notify the local MPU via interrupt if so enabled.
Double Bit Error (Cycle Type = Scrub)
1. Do not perform the write portion of the cycle. (This causes the
location to continue to indicate a non-correctable error when
accessed.)
2. Log the error if not already logged.
3. Notify the local MPU via interrupt if so enabled.
Triple (or Greater) Bit Error (Cycle Type = Scrub)
Some of these errors are detected correctly and are treated the same as a
double-bit error. The rest may show up as "no error" or "single-bit error",
both of which are incorrect.
