Address Mapping
Physical Address Mapping
Address field (SDCCRn.BA[35:21]) of the SDRAM Channel Control Register and the Address
Mask Field (SDCCRn.AM[35:21]).
AND of each bit, and "!" represents the logical NOT of each bit.
bus controllers or PCI controllers are simultaneously selected.
It is possible to map each of the four channels to an arbitrary physical address using the Base
The channel that becomes True in the following equation is selected.
In the above equation, "paddr" represents the accessed physical address, "&" represents the
Operation is undefined when multiple channels are simultaneously selected, or when external
paddr[35:21] & !AM[35:21] = BA[35:21] & !AM[35:21]
