Upon detection of an error condition, the controller corrects the error as quickly as possible. Therefore, the report information is actually generated after the correction has taken place, assuming it is possible to correct the error. The following scenarios exist:
Diagnosis: CRC error only [cannot identify location or number of bits in error]
SC 04
CRC
Diagnosis: Enhanced repair checksum buffer uncorrectable error
SC 04
BFR
Diagnosis: 1-bit ECC error, SYNDROME is valid. Controller reports physical frame address, linear frame address, word in frame, and bit in word.
SC 04
SED OK
PA {8-digit hex value}
LA {8-digit hex value}
WD {2-digit hex value} BT {2-digit hex value}
Diagnosis: 1-bit ECC error, SYNDROME is invalid, unexpectedly indicating an out-of-range word address. Controller reports physical frame address and linear frame address. If this diagnosis code occurs, the FPGA must be reconfigured.
SC 04
SED NG
PA {8-digit hex value}
LA {8-digit hex value}
Diagnosis: 2-bit ECC error. Controller reports physical frame address and linear frame address.
SC 04
DED
PA {8-digit hex value}
LA {8-digit hex value}
