MCECC

EALT EALT indicates that the last logging of an error occurred on a DRAM access by an alternate (MI* not asserted) local bus master.

ESCRB ESCRB indicates the entity that was accessing DRAM at the last logging of a single or double bit error. If ESCRB is 1, it indicates that the scrubber was accessing DRAM. If ESCRB is 0, it indicates that the local MC68060 bus master was accessing DRAM.

ERD ERD reflects the state of the local bus READ signal pin at the last logging of a single or double bit error. ERD = 1 corresponds to READ = high and ERD = 0 to READ = low. ERD is meaningless if ESCRB is set.

ERRLOG When set, ERRLOG indicates that a single or a double bit error has been logged by this MCECC, and that no more is logged until it is cleared. The bit can only be set by logging an error and cleared by writing a one 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 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 MC68060 address bus at the last logging of an error.
