I'm using ATmega32. This two timers looks very similar. What is a difference between them? When should I use Timer0, and when Timer2?

\$\begingroup\$ Probably one of the two can be routed to the UART peripheral. I didn't check the datasheet, but that is what I remember from a similar search a while ago. There are probably other similar differences. \$\endgroup\$– jippieMar 4, 2014 at 6:32

Timer2 is async timer. It means it can count when sleeping. But it's tricky to setup it when external clock is required. When external clock source is to be used a few pulses to setup it correctly is needed. I.e. it limits timer2 counter to be used as random pulse counter.
