  14 SAM-BA boot-assistant can be used (not through this module) by setting PA0, PA1, and PA2 high for at least 10 seconds followed by a power cycle.  SAM-BA supports reprogramming through the DBGU port or USB port.
  15
  16 The System Controller peripherals are all mapped to the highest 4 Kbytes of address space,
  17 between addresses 0xFFFF F000 and 0xFFFF FFFF.
