Flash and ISP specification
AVR UC3 devices with the USB feature are shipped with a USB bootloader.
This USB bootloader allows to perform In-System Programming (ISP) from a USB host control-
ler without removing the part from the system, without a pre-programmed application and
without any external programming interface other than USB.
There is one bootloader compiled for each AVR UC3 serie. The hardware I/O conditions used to
request the start of the ISP are also specific to each serie.
This document describes the USB bootloader functionalities and its usage in various contexts.
This documentation applies to the following AVR UC3 parts:

Note:
The bootloader is compiled for each AVR UC3 A0, A1, A3, B0, B1 series because of differences
in the MCU peripheral memory map. The functionalities are the same between all series.
