Address:
Default:
If booting from Asynchronous ROM, asynchronous memory bank zero (nCS0) is mapped to
address 0x0000_0000. If booting from SyncROM or SyncFLASH, Synchronous Memory
Domain 3 (nSDCS3) is re-mapped to address 0x0000_0000. This re-mapping of nSDCS3
does not change until after the boot process is completed and the processor is reset (not
power-on reset). At that time, nSDCS3 is mapped back to address 0xF000_0000, the
beginning address of Synchronous Memory Domain 3.

Note: 8-bit wide bus is not supported for SyncROM or SyncFLASH.
