MCECC Functions

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.
