Scrub Address Counter (Bits 7-4)
This register reflects the current value in the Scrub Address Counter bits
7-4.
Error Logger Register
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.
