Playground :: Timer1 ::

Hi,
I am not sure if this is the right part of the forum.

Anyhow I am struggeling with the calculation of the max period time of Timer1.

The calculation below the timing table says:

In general:
•Max Period = (Prescale)(1/Frequency)(2^17)
•Time per Tick = (Prescale)*(1/Frequency)

As this timer is a 16 bit (65535 counts) I am struggeling with the idea of 2^17 ...this would be 17 bit (131070 counts), wouldn't it? Therefore the max period would be wrong as well...

I am right? If not pls have a short explanation.

Please check - Gammon Forum : Electronics : Microprocessors : Timers and counters - for a very good explanation
