Reset Input. A low level on this pin for longer than the minimum pulse length will generate a
reset, even if the clock is not running. The minimum pulse length is given in
296. Shorter pulses are not guaranteed to generate a reset.
Input to the inverting Oscillator amplifier and input to the internal clock operating circuit.
Output from the inverting Oscillator amplifier.
AVCC is the supply voltage pin for Port A and the A/D Converter. It should be externally con-
nected to V
through a low-pass filter.
AREF is the analog reference pin for the A/D Converter.

Note:
Reliability Qualification results show that the projected data retention failure rate is much less
than 1 PPM over 20 years at 85°C or 100 years at 25°C.
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 documen-
tation for more details.
