Hi, what should be the fuses settings on my Atmega 328p if I dlike to use external passive crystal on 11.0592MHz? It is connected on its XTAL 1 and 2 pins.
I find this website useful for working out fuse settings:

Thank you for your reply, I know this calculator, but if someone can help I'm not familiar with all of its options (ext. oscylator, full swing oscylator, low freq oscylator ect.)
Get a Parallel ROM Programmer, consult the following Table of Fig-1, and then proceed to program the fuse bits as needed to operate the ATmega328P with external oscillator.
CKSEL2 - CKSEL0 are the Clock Selection Fuse Bits as per above Table 13-1.
Figure-1:
As I said before I'm not familiar with these tables, I cant get the answer which are my settings for 11,0592Mhz crystal. in these tables I see only 8 Mhz! I expect someone to say Low fuse= DE, or Low fuse=62 ...
For 11.xxMHz, you should probably use the "low power crystal oscillator."
I believe that that ends up being the same settings as the Arduino defaults for the ATmega328p (ie there isn't any difference in fuses needed to go from 16MHz to 11.xMHz.)

Read post #6 @westfw and set Low Fuse at 0xFF according to Fig-1 of post #4.
