2. Because a 2-bit prescaler in the timer must count four internal cycles (t
CYC
), this is the limiting
minimum factor in determining the timer resolution.
3. The minimum period t
should not be less than the number of cycle times it takes to execute
the capture interrupt service routine plus 24 t
.
4. The minimum t
should not be less than the number of cycle times it takes to execute the
interrupt service routine plus 19 t
