ATmega64(L)

2490L–AVR–10/06

RESET

Reset input. A low level on this pin for longer than the minimum pulse length will gener-

ate a reset, even if the clock is not running. The minimum pulse length is given in Table

19 on page 52. Shorter pulses are not guaranteed to generate a reset.

XTAL1

Input to the inverting Oscillator amplifier and input to the internal clock operating circuit.

XTAL2

Output from the inverting Oscillator amplifier.

AVCC

AVCC is the supply voltage pin for Port F 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 con-

nected to V

CC through a low-pass filter.

AREF

AREF is the analog reference pin for the A/D Converter.

PEN

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 has no function during normal operation.
