2.2.18 XTAL2

2.2.19 AVCC

2.2.20 AREF

Output from the inverting oscillator amplifier.

AVCC is the supply voltage pin for Port F and the A/D Converter. It should be externally con-

nected to VCC, even if the ADC is not used. If the ADC is used, it should be connected to VCC

through a low-pass filter.

This is the analog reference pin for the A/D Converter.

4. 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".
