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
1. Typical value reflect average measurements at midpoint of voltage range, 25 °C only. See
2. No more than 10% duty cycle deviation from 50%.
3. Fundamental mode crystals only.
4. Consult crystal vendor data sheet.
5. Not required for high frequency crystals.
