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