Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.

ctrlcfg0 Fields

Bit Name Description Access Reset
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
RW 0x0
18:14 cfg_dbc0_burst_length
Configures burst length for DBC0. 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
13:9 cfg_ctrl_burst_length
Configures burst length for control path. 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
8:7 cfg_ac_pos
Specify C/A (command/address) pin position. 2
RW 0x0
6:4 cfg_dimm_type
Selects dimm type. Program this field with one of the following binary values, "3
RW 0x0
3:0 cfg_mem_type
Selects memory type. Program this field with one of the following binary values, "0000" for DDR3 SDRAM, "0001" for DDR4 SDRAM, and "0011" for RLDRAM3.
