3.2.5 AHB memory alias for low memory
Normally, fast dynamic memory resides at location
0x00000000
. This area is used to
store exception vector tables. Address remap functionality is provided to temporarily
map an alias of another memory region to
0x00000000
–
0x03FFFFFF
after a power-on reset.
The memory map outside the
0x00000000
to
0x03FFFFFF
address range is only controlled
by MPMCnSMC and CFGBRIDGEMEMMAP. Except for Figure 3-13 and
Figure 3-16 on page 3-27, all figures show the memory map for MPMCnSMC LOW
and CFGBRIDGEMEMMAP LOW.
Figure 3-13 summarizes the effects of the remap signals on the AHB data and
instruction buses.
Note
Only the combination of REMAPEXTERNAL HIGH and CFGBRIDGEMEMMAP
LOW result in different mappings for the ARM I AHB master and the ARM D AHB
master.
