For more information about the lower 2-GiB programmable interleaving model of the MA_LSM, see the Dynamic Mapping, and Address Mapping sections in Section 17.2, Dynamic Memory Manager. When reading, replace DMM with MA_LSM.
The MA_LSM is associated with the lower 2GiB shared memory space, that is, emif(a) and emif(b). In this case there is programmable interleaving (128B, 256B and 512B) and programmable MPU-to-EMIF address mapping configured trough the MA_LISA_MAP_i registers.
The MA_LSM is NOT associated with the 6GiB of MPU-only memory, that is, Emif(c) through Emif(h). In this case there is fixed interleaving (256B only) and fixed MPU-to-EMIF address mapping which cannot be programmed using the MA_LISA_MAP_i registers because MA_LSM is not used with address ranges greater than 2GiB. The fixed MPU-to-EMIF address mapping is shown in Figure 4-7 and Figure 4-8.
