On-Chip Memory

Only one of these vector maps—M0 vector, PIE vector, BROM vector, XINTF vector—should be enabled at a time.

L3 SARAM (1K × 16)

NOTES: A. Memory blocks are not to scale.

B. Reserved locations are reserved for future expansion. Application should not access these areas.

C. 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.

D. “Protected” means the order of Write followed by Read operations is preserved rather than the pipeline order.

E. Certain memory ranges are EALLOW protected against spurious writes after configuration.

F. The passwords are set to all ones.
