This is the ARM7 series of microcontrollers from Atmel, including:
* AT91SAM7S512
* AT91SAM7S256
* AT91SAM7S128
* AT91SAM7S64
* AT91SAM7S321
* AT91SAM7S32
* AT91SAM7S161
* AT91SAM7S16

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.

The System Controller peripherals are all mapped to the highest 4 Kbytes of address space,
between addresses 0xFFFF F000 and 0xFFFF FFFF.
