Configures the system address mapping options.
The address_map_next register characteristics are:
- Usage constraints
Can be read from when in ALL states. Can be written to when in ALL states.
There is only one DMC configuration.
The following figure shows the bit assignments.
Figure 3-6 address_map_next register bit assignments
The following shows the bit assignments.
- [31:16] addr_map_mask_next
Configures the mask applied to system address bits [43:28]. The system address map uses upper address bits to select from multiple DMC instances in a system. The DMC must discard these address bits that fall outside physical memory to decode correctly.
- [15:3] Reserved_1
- [2:0] addr_map_mode_next
Selects the address translation mode. See the System Address Conversion section of the Design Manual for more information on address translation options.
