Configures the system address mapping options.
The address_map_now register characteristics are:
- Usage constraints
Can be read from when in ALL states. Cannot be written to and only updated when in CONFIG or LOW-POWER states.
There is only one DMC configuration.
The following figure shows the bit assignments.
Figure 3-191 address_map_now register bit assignments
The following shows the bit assignments.
- [31:16] addr_map_mask_now
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_now
Selects the address translation mode. See the System Address Conversion section of the Design Manual for more information on address translation options.
