WLPRD
|
Write leveling period: returns the DDR clock period measured by the write leveling LCDL during calibration of byte 0. 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.

Write leveling system latency: used to adjust the write latency of byte 0 after write leveling. Valid values: 0000: Write latency = WL-1 DRAM clock period 0001: Write latency = WL-0.5 DRAM clock period 0010: Write latency = WL 0011: Write latency = WL+0.5 DRAM clock period 0100: Write latency = WL+1 DRAM clock period 0101: Write latency = WL+1.5 DRAM clock period 0110: Write latency = WL+2 DRAM clock period 0111: Write latency = WL+2.5 DRAM clock period 1000: Write latency = WL+3 DRAM clock period 1001: Write latency = WL+3.5 DRAM clock period 1010: Write latency = WL + 4 DRAM clock period 1011 - 1111: RESERVED
Write DQS are pipelined according to the table above.
Note: Write data carries additional pipeline delay according to WDQSL.
