1. V
2. Some modules may require a minimum frequency greater than dc for proper operation; see appropriate table for this infor-
3. Minimum pulse width reset is guaranteed to be recognized. It is possible for a smaller pulse width to cause a reset.
1. No more than 10% duty cycle deviation from 50%
2. Consult crystal vendor data sheet
3. Not Required for high frequency crystals
