28:24 | cfg_dbc2_burst_length | Configures burst length for DBC2. Legal values are valid for JEDEC allowed DRAM values for the DRAM selected in cfg_type. For DDR3 and DDR4, this should be programmed with 8 (binary "01000"), for RLDRAM III it can be programmed with 2 or 4 or 8 |
RW | 0x0 |
23:19 | cfg_dbc1_burst_length | Configures burst length for DBC1. Legal values are valid for JEDEC allowed DRAM values for the DRAM selected in cfg_type. For DDR3 and DDR4, this should be programmed with 8 (binary "01000"), for RLDRAM III it can be programmed with 2 or 4 or 8 |
