CONTROL TIMING
NOTES:
1. The 2-bit timer prescaler is the limiting factor in determining timer resolution.
2. 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
.
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
