DFITMG2 (DDRC) Register Bit-Field Summary
Field Name | Bits | Type | Reset Value | Description |
---|---|---|---|---|
dfi_tphy_rdcslat | 13:8 | rwNormal read/write | 0x2 | >Number of clocks between when a read command is sent on the DFI control interface and when the associated dfi_rddata_cs signal is asserted. This corresponds to the DFI timing parameter tphy_rdcslat. This should be set to dfi_t_rddata_en - 2. |
dfi_tphy_wrcslat | 5:0 | rwNormal read/write | 0x2 | Number of clocks between when a write command is sent on the DFI control interface and when the associated dfi_wrdata_cs signal is asserted. This corresponds to the DFI timing parameter tphy_wrcslat. For non-RDIMM systems, this should be set to dfi_tphy_wrlat-5. For RDIMM systems, this should be set to 2. |
