NOTES:
1. The minimum period t_ILIL or t_IHIH should not be less than the number of cycles it takes to
execute the interrupt service routine plus 19 t_CYC.
2. The 2-bit timer prescaler is the limiting factor in determining timer resolution.
3. The minimum period t_TLTL should not be less than the number of cycles it takes to execute
the capture interrupt service routine plus 24 t_CYC.
