With dual mapping, aliasing of address spaces may occur. This happens when the region is dual-mapped
into a region which is also mapped into one of the four regions available in the memory controller. If code
or data is written to the dual-mapped region, care must be taken to avoid overwriting this code or data by
normal accesses of the chip-select region.
There is a match if:
Care must also be taken to avoid overwriting “normal” CSx data with dual-mapped code or data.
One way to avoid this situation is by disabling the chip-select region and enabling only the dual-mapped
region (DMBR[DME] = 1, but BRx[V] = 0).

The attributes for the access are taken from one of the base and option registers of the appropriate
chip select
The chip-select region selected is determined by the CS line select bit field
“Dual-Mapping Base Register
where BA represents the bit field in the DMBR register.
