DX2GSR2 (DDR_PHY) Register Bit-Field Summary
| Field Name | Bits | Type | Reset Value | Description |
|---|---|---|---|---|
| GSDQSPRD | 31:23 | roRead-only | 0x0 | Read DQS gating Status Period: Returns the DDR clock period measured by the read DQS gating status LCDL during calibration. This value is PVT compensated. |
| GSDQSCAL | 22 | roRead-only | 0x0 | Read DQS Gating Status Calibration: Indicates, if set, that the DATX8 has finished doing period measurement calibration for the read DQS gating status LCDL. |
| Reserved | 21 | roRead-only | 0x0 | Reserved. Return zeroes on reads. |
| DQS2DQERR | 15:12 | roRead-only | 0x0 | Write DQS2DQ training error: Indicates, if set, that the DATX8 has encountered an error during execution of the write DQS2DQ training Each 2 bits indicate error on one rank. (e.g. bits [13:12] shows error on rank 0) Status encoding are: 2'b00: No Error 2'b01: Oscillator results are all 0s 2'b10: Oscillator results are all 1s 2'b11: Oscillator results read timeout |
| ESTAT | 11:8 | roRead-only | 0x0 | Error 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 | 7 | roRead-only | 0x0 | Write Eye Centering Warning: Indicates, if set, that the DATX8 has encountered a warning during execution of the write eye centering training. |
| WEERR | 6 | roRead-only | 0x0 | Write Eye Centering Error: Indicates, if set, that the DATX8 has encountered an error during execution of the write eye centering training. |
| REWN | 5 | roRead-only | 0x0 | Read Eye Centering Warning: Indicates, if set, that the DATX8 has encountered a warning during execution of the read eye centering training. |
| REERR | 4 | roRead-only | 0x0 | Read Eye Centering Error: Indicates, if set, that the DATX8 has encountered an error during execution of the read eye centering training. |
| WDWN | 3 | roRead-only | 0x0 | Write Bit Deskew Warning: Indicates, if set, that the DATX8 has encountered a warning during execution of the write bit deskew training. |
| WDERR | 2 | roRead-only | 0x0 | Write Bit Deskew Error: Indicates, if set, that the DATX8 has encountered an error during execution of the write bit deskew training. |
| RDWN | 1 | roRead-only | 0x0 | Read Bit Deskew Warning: Indicates, if set, that the DATX8 has encountered a warning during execution of the read bit deskew training. |
| RDERR | 0 | roRead-only | 0x0 | Read Bit Deskew Error: Indicates, if set, that the DATX8 has encountered an error during execution of the read bit deskew training. |
