A comprehensive set of development tools, application notes and datasheetsare available for
download on http://www.atmel.com/avr.
This documentation contains simple code examples that briefly show how to use various parts of
the device. Be aware that not all C compiler vendors include bit definitions in the header files
and interrupt handling in C is compiler dependent. Please confirm with the C compiler documen-
tation for more details.
The code examples assume that the part specific header file is included before compilation. For
I/O registers located in extended I/O map, "IN", "OUT", "SBIS", "SBIC", "CBI", and "SBI" instruc-
tions must be replaced with instructions that allow access to extended I/O. Typically "LDS" and
"STS" combined with "SBRS", "SBRC", "SBR", and "CBR".
Reliability Qualification results show that the projected data retention failure rate is much less
than 1 PPM over 20 years at 85°C or 100 years at 25°C.
