Notes:
1. The minimum period tILIL should not be less than the number of cycle times it takes to execute the
IRQ interrupt service routine plus 21tCYC.
2. Depending on the active edge of TCAP, either tTH, the high TCAP pulse width, or tTL, the low
TCAP pulse width applies.
3. The minimum period tTLTL should not be less than the number of cycle times it takes to execute
the input capture interrupt service routine plus 24tCYC.
