Apply chip features to see fuse bit settings or apply fuse bit settings to match against known features. Avr hardware design considerations which i linked in an answer to one of your previous questions.
Https Www Avrfreaks Net Forum Difference Between Full Swing And Ext Oscill Setting
Using a crystal oscillator to provide the clock input is shown in section 10 of the atmega2560 datasheet as you linked.
Atmega full swing oscillator vs. However in the new atmega328pb the full swing crystal oscillator is removed. Clock source options of the atmega328 variants include full swing crystal oscillator which can be selected by configuring the flash fuse. The full swing oscillator driver circuitry is being removed.
Project learn about atmega328p fuse bits and how to use them with an external crystal oscillator august 03 2017 by charles r. As always theres good news and bad news. A javascript web based atmel avr microcontroller fuse calculator tool.
It is also discussed in the atmel application note. Low frequency crystal oscillator 0100 through 0101 full swing crystal oscillator 0110 through 0111 low power crystal oscillator 1000 through 1111. Apparently low power crystal oscillator is so standard they just call it ext.
The older atmega chips had two different crystal drivers a low power one that worked for lower speeds and higher current version that would make even recalcitrant crystals with fat loading capacitors sing. You can tell because of the cksel ranges in the datasheet. And the atmega itself will put a lot of capacitance on the pins perhaps 4 to 10pf or so each.
Apr 13 2017 1056 pm. Refer to the clock sources chapter of the respective datasheet. Generic 22pf discrete caps to get to the 30 to 36pf ballpark.
Note that the full swing crystal oscillator will only operate for vcc 27 55 volts. The low frequency crystal oscillator is designed for use at 32768khz very slow but often adequate in low power low frequency sensing applications. The pb doesnt have the full swing oscillator and the low power oscillator tops out at 16mhz so 20 mhz crystals wont work anymore.
With ground in the middle but from the xtals point of view they are simply in series. Hampton this project introduces atmega328p fuse bits and shows how to set them to use an external 16 mhz crystal oscillator.
