ATTINY26 Application --external crystal, 10MHz
What is the purpose of the CKOPT fuse?!?...it seems to increase the external crystal drive level (which I need to have so I can drive a buffer clock gate from the crystal).
However I can find no info/specs on this feature.
Also in many places the manual says when NOT to set it, but not when TO set it. Am I getting in trouble by setting it? It seems to be working fine & my logic buffer is happy too.
