I have been reading the data sheets of the various 8 bit avr devices that I use trying to understand just how they are programmed.
All can be programmed by SPI Programming Interface.
I can not see what part of the data sheet describes this.
I can not find the right application note on Atmels Web site.
Would someone be as kind as to point me in the right direction.
What I want to know are the signals and timming applied to each pin during programming.
