This documentation contains simple code examples that briefly show how to use various parts of
the device. These code examples assume that the part specific header file is included before
compilation. 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.
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”.
Atmel QTouch Library provides a simple to use solution for touch sensitive interfaces on Atmel
AVR microcontrollers. The QTouch Library includes support for QTouch
tion methods.
Touch sensing is easily added to any application by linking the QTouch Library and using the
Application Programming Interface (API) of the library to define the touch channels and sensors.
The application then calls the API to retrieve channel information and determine the state of the
touch sensor.
The QTouch Library is free and can be downloaded from the Atmel website. For more informa-
tion and details of implementation, refer to the QTouch Library User Guide – also available from
the Atmel website.
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.
Typical values contained in this datasheet are based on simulations and characterization of
other AVR microcontrollers manufactured on the same process technology.
