1.
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.
2.
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.
3.
The minimum tILIL should not be less than the number of cycle times it takes to execute the interrupt service routine
plus 19 tCYC.
