USB Pads Internal Regulator Input supply voltage.
USB Pads Internal Regulator Output supply voltage. Should be connected to an external capac-
itor (1µF).
USB VBUS monitor input.
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
50. 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 (input) for all the A/D Converter channels. If the ADC is not used,
it should be externally connected to V
through a low-pass filter.
This is the analog reference pin (input) for the A/D Converter.
CC
. If the ADC is used, it should be connected to V
