AVCC

AREF

The various special features of Port E are elaborated in “Alternate Functions of Port E”

on page 78 and “Clock Systems and their Distribution” on page 30.

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

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

nected to VCC through a low-pass filter.

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. These code examples assume that the part specific header file is

included before compilation. Be aware that not all C compiler vendors include bit defini-

tions in the header files and interrupt handling in C is compiler dependent. Please

confirm with the C compiler documentation for more details.
