Field NameBitsTypeReset ValueDescription
GSDQSPRD31:23roRead-only0x0Read DQS gating Status Period: Returns the DDR clock period
measured by the read DQS gating status LCDL during calibration.
This value is PVT compensated.
GSDQSCAL22roRead-only0x0Read DQS Gating Status Calibration: Indicates, if set, that the
DATX8 has finished doing period measurement calibration for the
read DQS gating status LCDL.
Reserved21roRead-only0x0Reserved. Return zeroes on reads.
ESTAT11:8roRead-only0x0Error Status: If an error occurred for this lane as indicated by
RDERR, WDERR, REERR or WEERR the error status code can
provide additional information regard when the error occurred
during the algorithm execution.
WEWN 7roRead-only0x0Write Eye Centering Warning: Indicates, if set, that the DATX8 has
encountered a warning during execution of the write eye centering
training.
WEERR 6roRead-only0x0Write Eye Centering Error: Indicates, if set, that the DATX8 has
encountered an error during execution of the write eye centering
training.
REWN 5roRead-only0x0Read Eye Centering Warning: Indicates, if set, that the DATX8 has
encountered a warning during execution of the read eye centering
training.
REERR 4roRead-only0x0Read Eye Centering Error: Indicates, if set, that the DATX8 has
encountered an error during execution of the read eye centering
training.
WDWN 3roRead-only0x0Write Bit Deskew Warning: Indicates, if set, that the DATX8 has
encountered a warning during execution of the write bit deskew
training.
WDERR 2roRead-only0x0Write Bit Deskew Error: Indicates, if set, that the DATX8 has
encountered an error during execution of the write bit deskew
training.
RDWN 1roRead-only0x0Read Bit Deskew Warning: Indicates, if set, that the DATX8 has
encountered a warning during execution of the read bit deskew
training.
RDERR 0roRead-only0x0Read Bit Deskew Error: Indicates, if set, that the DATX8 has
encountered an error during execution of the read bit deskew
training.
