Greets to all!
I've been working thru the Atmel 328 manual studying the timers, and seem to have a fair understanding of most of the registers and settings. One that is giving me a bit of confusion is the setting for "0 Prescale". From the datasheet it says on all 3 counters that this should provide CLK_io which I take to be the 16mhz on the Arduino Uno.
I am only studying interrupts and have a scope set for rise-to-fall period measurements. With zero prescale I'm expecting to get a 62.5 nano-sec pulse - but what I'm seeing is much slower. I've tried on all 3 timers... and still never see that 16mhz period. Obviously I've missed a very important concept along the way. All the other timer/prescale settings work in a fairly predictable manner - just the PS0 is bumming me out! Any ideas?
