Field Name | Bits | Type | Reset Value | Description |
---|---|---|---|---|
odtloff | 30:24 | rwNormal read/write | 0x1C | LPDDR4: tODTLoff: This is the latency from CAS-2 command to tODToff reference. Program this to (tODTLoff/2) and round it up to next integer value. Unit: Clocks. |
t_ccd_mw | 21:16 | rwNormal read/write | 0x20 | LPDDR4: tCCDMW: This is the minimum time from write or masked write to masked write command for same bank. Program this to (tCCDMW/2) and round it up to next integer value. Unit: Clocks. |
t_ppd | 2:0 | rwNormal read/write | 0x4 | LPDDR4: tPPD: This is the minimum time from precharge to precharge command. Program this to (tPPD/2) and round it up to next integer value. Unit: Clocks. |
