SBE SINGLE BIT ERROR is set when the last error logged was due to a single bit error. It is cleared when a 1 is written to the ERRLOG bit. The syndrome code reflects the bit in error. (Refer to the section on Syndrome Decode.)

MBE MULTIPLE BIT ERROR is set when the last error logged was due to a multiple bit error. It is cleared when a 1 is written to the ERRLOG bit. The syndrome code is meaningless if MBE is set.

ERA This bit provides status for a function that is not currently used in the MCECC.
