• Communication via the USB Device Port is limited to an 18.432 MHz crystal.
The SAM-BA Boot provides an interface with SAM-BA Graphic User Interface (GUI).
The SAM-BA Boot is in ROM and is mapped at address 0x0 when the GPNVM Bit 2 is set to 0.
When GPNVM bit 2 is set to 1, the device boots from the Flash.
When GPNVM bit 2 is set to 0, the device boots from ROM (SAM-BA).
