Single-bit DRAM ECC Error Flag (DSERR)—R/WC.

sent for the access. When this bit is set, the address, channel number, and device number
that caused the error are logged in the EAP register. Once this bit is set, the EAP fields are
locked to further single bit error updates until the processor clears this bit by writing a 1 to it. A
multiple bit error that occurs after this bit is set will overwrite the EAP fields with the multiple
bit error signature and the MEF bit will also be set. Software must write a 1 to clear this bit and
unlock the error logging mechanism.
