32166A–AVR32806–06/11
Atmel AVR32806
Devices delivered with version 1.1.1
:
•
Atmel AVR UC3 C, rev. D and higher
Known bugs and limitations
: The frequency detection feature does not integrate the
excursion of the RCSYS (±3%).
8.1.5 Version 1.1.0 - 2010/01/15
•
Optimized auto-baud implementation to save memory footprints
•
Removed serial number upon USB DFU enumeration to support USB gang-
programming from the same platform
•
Removed usage of the configuration general purpose fuse bit ISP_BOD_EN: This
implies that the BOD is not enabled by the boot loader
•
Moved usage of the configuration general purpose fuse bits ISP_IO_COND_EN and
ISP_FORCE to bits in the last word of the user page, this word being referred to as
Configuration Word1
•
Use the penultimate word of the user page to store the I/O conditions boot loader
configuration, this word being referred to as Configuration Word2
Supported devices
