2. Minimum pulse width reset is guaranteed to be recognized. It is possible for a smaller pulse width to cause a reset.
3. Values are based on characterization results, not tested in production.
4. The minimum period is the number of cycles it takes to execute the interrupt service routine plus 1 t
