1. The minimum period t_ILIL should not be less than the number of cycle times it takes to execute the
IRQ interrupt service routine plus 21t_CYC.
2. Depending on the active edge of TCAP, either t_TH, the high TCAP pulse width, or t_TL, the low
TCAP pulse width applies.
3. The minimum period t_TLTL should not be less than the number of cycle times it takes to execute
the input capture interrupt service routine plus 24t_CYC.
