Bit
a. <brc_n_rbc>
b. <address_match>
c.
Note: When you set the start address, refer to the section 3.3 Memory Map, and confirm valid areas.
21. dmc_chip_0_cfg_3 (DMC chip_0_cfg Registers)
SDRAM address structure:
0y0 = row, bank, column
0y1 = bank, row, column
Set the start address [31:24].
Do not access DMC area (Not used) except for configured CS area, if you accessed to
memory less than 512 MB.
Set the CS areas.
Determine which bit in the start address should be or should not be compared.
0y0 = Not compare
0y1 = Compare
Setting example
<address_mask>
512MB CS area : <address_mask [7:0]> = 0y11100000
16MB CS area : <address_mask [7:0]> = 0y11111111
32MB CS area : <address_mask [7:0]> = 0y11111110
