9.2 Memory Maps
In 图9-1, 图9-2, 图9-3, 图9-4, and 图9-5, the following apply:
• Memory blocks are not to scale.
• Peripheral Frame 0, Peripheral Frame 1 and Peripheral Frame 2 memory maps are restricted to data memory
only. A 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.
• Locations 0x3D7C80 to 0x3D7CC0 contain the internal oscillator and ADC calibration routines. These
locations are not programmable by the user.
