The error correction process varies depending on the controller configuration and the nature of what has been detected and what can be corrected.
The general form of the report for an uncorrectable error, or when correction is disabled is:
COR
END
Followed by:
FC 20 Bit 5, uncorrectable set (stale essential flag)
or
FC 60 Bit 5, uncorrectable set (stale essential flag)
The general form of the report for a correctable error is:
COR
{correction list}
END
Followed by:
FC 00 Bit 5, uncorrectable cleared (stale essential flag)
or
FC 40 Bit 5, uncorrectable cleared (stale essential flag)
The {correction list} is one or more lines providing the word in frame and bit in word of each corrected bit. The list can potentially be thousands of lines. This is the same notation used for the error detection report. Each line of the list is formatted as follows:
WD {2-digit hex value} BT {2-digit hex value}
