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
52. 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 F 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.
This is a programming enable pin for the SPI Serial Programming mode. By holding this pin low
during a Power-on Reset, the device will enter the SPI Serial Programming mode. PEN is inter-
nally pulled high. The pullup is shown in
“DC Characteristics” on page
CC
, even if the ADC is not used. If the ADC is used, it should be connected to V
325. PEN has no function during normal operation.
