The MATRIX provides one decoder for every AHB master interface. The decoder offers each AHB master several memory mappings. Each memory area may be assigned to several slaves. Thus booting at the same address while using different AHB slaves (i.e., external RAM, internal ROM or internal Flash, etc.) is possible.
The MATRIX user interface provides the Master Remap Control Register (MATRIX_MRCR) that performs remap action for every master independently.
