2. Some modules may require a minimum frequency greater than dc for proper operation; see appropriate table for this
3. Minimum pulse width reset is guaranteed to be recognized. It is possible for a smaller pulse width to cause a reset.
1. The USB module is designed to operate with f
2. No more than 10% duty cycle deviation from 50%.
3. Consult crystal vendor data sheet.
