DX1GSR0 (DDR_PHY) Register Bit-Field Summary

Field NameBitsTypeReset ValueDescription
Reserved31roRead-only0x0Reserved. Returns zeroes on reads.
WLDQ30roRead-only0x0Write Leveling DQ Status: Captures the write leveling DQ status
from the DRAM during software write leveling.
Reserved29:26roRead-only0x0Reserved. Returns zeroes on reads.
GDQSPRD25:17roRead-only0x0Read DQS gating Period: Returns the DDR clock period measured
by the read DQS gating LCDL during calibration. This value is PVT
compensated.
WLPRD15:7roRead-only0x0Write 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 6roRead-only0x0Write Leveling Error: Indicates, if set, that there is a write leveling
error in the DATX8.
WLDONE 5roRead-only0x0Write Leveling Done: Indicates, if set, that the DATX8 has
completed write leveling.
WLCAL 4roRead-only0x0Write Leveling Calibration: Indicates, if set, that the DATX8 has
finished doing period measurement calibration for the write leveling
slave delay line.
GDQSCAL 3roRead-only0x0Read DQS gating Calibration: Indicates, if set, that the DATX8 has
finished doing period measurement calibration for the read DQS
gating LCDL.
RDQSNCAL 2roRead-only0x0Read DQS# Calibration: Indicates, if set, that the DATX8 has
finished doing period measurement calibration for the read DQS#
LCDL.
RDQSCAL 1roRead-only0x0Read DQS Calibration: Indicates, if set, that the DATX8 has
finished doing period measurement calibration for the read DQS
LCDL.
WDQCAL 0roRead-only0x0Write DQ Calibration: Indicates, if set, that the DATX8 has finished
doing period measurement calibration for the write DQ LCDL.
