Bit Range | Default | Access | Field Name and Description |
---|---|---|---|
31:24 | 0x4 | RW | tRDRD Different DIMM (tRDRD_dd) Minimum delay from RD to RD to the other DIMM in tCK (WCK for LPDDR5) cycles. |
23:16 | 0x4 | RW | tRDRD Different Rank (tRDRD_dr) Minimum delay from RD to RD to the other rank in the same DIMM in tCK (WCK for LPDDR5) cycles. |
15 | 0h | RO | Reserved |
14:8 | 0x4 | RW | tRDRD Different Group (tRDRD_dg) LPDDR4/LPDDR5: Minimum delay from RD to RD to different banks in tCK (WCK for LPDDR5) cycles. |
7 | 0x1 | RW | Allow 2 Cycle B2B LPDDR (Allow_2cyc_B2B_LPDDR) LPDDR4/LPDDR5: in MPR mode reads work on BL16. |
6:0 | 0x4 | RW | tRDRD Same Group (tRDRD_sg) LPDDR4/LPDDR5: Minimum delay from RD to RD to the same bank in tCK (WCK for LPDDR5) cycles. |
