   4 This is the ARM7 series of microcontrollers from Atmel, including:
   5 * AT91SAM7S512
   6 * AT91SAM7S256
   7 * AT91SAM7S128
   8 * AT91SAM7S64
   9 * AT91SAM7S321
  10 * AT91SAM7S32
  11 * AT91SAM7S161
  12 * AT91SAM7S16
  13
  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.
