NOTES: A. Memory blocks are not to scale.
B. Reserved locations are reserved for future expansion. Application should not access these areas.
C. Boot ROM and Zone 7 memory maps are active either in on-chip or XINTF zone depending on MP/MC, not in both.
D. Peripheral Frame 0, Peripheral Frame 1, and Peripheral Frame 2 memory maps are restricted to data memory only. User program
cannot access these memory maps in program space.
E. “Protected” means the order of Write followed by Read operations is preserved rather than the pipeline order.
F. Certain memory ranges are EALLOW protected against spurious writes after configuration.
G. Zones 0 and 1 and Zones 6 and 7 share the same chip select; hence, these memory blocks have mirrored locations.
