Atmel ATtiny24/44/84 [Preliminary]
A comprehensive set of development tools, driver and application notes, and datasheets are
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. 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 documentation for more details.
For I/O registers located in the 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.
