2.2.18
XTAL2
Output from the inverting oscillator amplifier.
2.2.19
AVCC
AVCC is the supply voltage pin for Port F and the A/D Converter. It should be externally con-
nected to V
CC, even if the ADC is not used. If the ADC is used, it should be connected to VCC
through a low-pass filter.
2.2.20
AREF
This is the analog reference pin for the A/D Converter.

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".
