The EMIF supports two local (on-chip) interfaces:
System interface is used to request all external memory device accesses, to access the EMIF registers, and to transfer all data to and from the EMIF controller. MPU interface is used to process memory accesses. Table 15-70 shows the MAddrSpace mapping.
MAddrSpace(1) | Chip-Select | Description | Exclusions |
---|---|---|---|
0x0 | CSN0 | SDRAM(s) | |
0x1 | N/A | Reserved. | |
0x2 | N/A | Reserved. Any access to this area will generate an error on the L3 interface. This can be used by the software to track any unwanted access to the section defined in the DMM_LISA_MAP_i register. | Not visible thtough the MPU port |
0x3 | N/A | Internal registers | Not visible through the MPU port |
