2. Because a 2-bit prescaler in the timer must count four internal cycles (tcyc), this is the limiting minimum factor in determining
the timer resolution.

3. The minimum period tTLTL should not be less than the number of cycle times it takes to execute the capture interrupt service
routine plus 24 tcyc.
