1. If all PQ’s are valid, ECC has successfully corrected single bit error, DQ contains Valid Data Out. If a PQ is invalid, ECC has
detected a multi-bit error, DQ’s for the corresponding byte contain invalid Data Out.
2. A parity error has been detected on data received from system. A subsequent read of this data will indicate a parity error (PQ
invalid). The operation of the error line during a write has not been characterized.
