About Code Examples

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.

These 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"

instructions must be replaced with instructions that allow access to extended I/O. Typically

"LDS" and "STS" combined with "SBRS", "SBRC", "SBR", and "CBR".

Data Retention

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.
