ERRLOG When set, ERRLOG indicates that a single- or a double-
bit error has been logged by this MCECC and that no
more will be logged until the error is cleared. The bit can
only be set by logging an error and cleared by writing a 1
to it. When ERRLOG is cleared, the MCECC is ready to
log a new error. Note that because hardware duplicates
control register writes to both MCECCs, clearing
ERRLOG in one MCECC sector clears it in the other. Any
available error information in either MCECC should be
recovered before clearing ERRLOG.

Error Address (Bits 31-24)
This register reflects the value that was on bits 31-24 of the local MC680x0
address bus at the last logging of an error.

Error Address (Bits 23-16)
This register reflects the value that was on bits 23-16 of the local MC680x0
address bus at the last logging of an error.
