DX3GSR0 (DDR_PHY) Register Bit-Field Summary
Field Name | Bits | Type | Reset Value | Description |
---|---|---|---|---|
Reserved | 31 | roRead-only | 0x0 | Reserved. Returns zeroes on reads. |
WLDQ | 30 | roRead-only | 0x0 | Write Leveling DQ Status: Captures the write leveling DQ status from the DRAM during software write leveling. |
Reserved | 29:26 | roRead-only | 0x0 | Reserved. Returns zeroes on reads. |
GDQSPRD | 25:17 | roRead-only | 0x0 | Read DQS gating Period: Returns the DDR clock period measured by the read DQS gating LCDL during calibration. This value is PVT compensated. |
WLPRD | 15:7 | roRead-only | 0x0 | Write Leveling Period: Returns the DDR clock period measured by the write leveling LCDL during calibration. The measured period is used to generate the control of the write leveling pipeline which is a function of the write-leveling delay and the clock period. This value is PVT compensated. |
WLERR | 6 | roRead-only | 0x0 | Write Leveling Error: Indicates, if set, that there is a write leveling error in the DATX8. |
WLDONE | 5 | roRead-only | 0x0 | Write Leveling Done: Indicates, if set, that the DATX8 has completed write leveling. |
WLCAL | 4 | roRead-only | 0x0 | Write Leveling Calibration: Indicates, if set, that the DATX8 has finished doing period measurement calibration for the write leveling slave delay line. |
GDQSCAL | 3 | roRead-only | 0x0 | Read DQS gating Calibration: Indicates, if set, that the DATX8 has finished doing period measurement calibration for the read DQS gating LCDL. |
RDQSNCAL | 2 | roRead-only | 0x0 | Read DQS# Calibration: Indicates, if set, that the DATX8 has finished doing period measurement calibration for the read DQS# LCDL. |
RDQSCAL | 1 | roRead-only | 0x0 | Read DQS Calibration: Indicates, if set, that the DATX8 has finished doing period measurement calibration for the read DQS LCDL. |
WDQCAL | 0 | roRead-only | 0x0 | Write DQ Calibration: Indicates, if set, that the DATX8 has finished doing period measurement calibration for the write DQ LCDL. |
