Where can you find the datasheet for Timer 3, 4, 5?

I have been searching for Timer 3, 4 and 5 from Atmel datasheets for a while now. But after downloading, the datasheets I kept getting only Timer 0, 1, 2. Where can you find the complete datasheet for Timer 3, 4, 5. Can you please give me a link for the pdf. Thank you.

Look at the datasheet for the specific processor; not all processors have those timers.

@sterretje Sir, thank you. Is there anyway to remove this post? I just realize by now that the answer was just this simple

It's best to leave the post. Other people may have the same question and benefit from finding it in a search.
