2.2.9

XTAL2

Output from the inverting Oscillator amplifier.

2.2.10

AVCC

AVCC is the supply voltage pin for Port A and the A/D Converter. It should be externally connected to V

CC

, even

if the ADC is not used. If the ADC is used, it should be connected to V

CC

through a low-pass filter.

2.2.11

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 definitions in the header files and interrupt handling in C is compiler

dependent. Please confirm with the C Compiler documentation for more details.
