3.1
Memory Maps
A.
Memory blocks are not to scale.
B.
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.
C.
Protected means the order of Write followed by Read operations is preserved rather than the pipeline order.
D.
Certain memory ranges are EALLOW protected against spurious writes after configuration.
