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
TLTL
should not be less than the number of cycle times it takes to execute the capture
interrupt service routine plus 24 t
CYC
.
4. The minimum t
ILIL
should not be less than the number of cycle times it takes to execute the interrupt service
routine plus 19 t
CYC
