Notes:
1. V_SS = 0 Vdc; timing shown with respect to 20% V_DD and 70% V_DD, unless otherwise noted.
2. See Table 21-8 and Table 21-9 for more information.
3. No more than 10% duty cycle deviation from 50%.
4. Some modules may require a minimum frequency greater than dc for proper operation; see appropriate table for this
information.
5. Minimum pulse width reset is guaranteed to be recognized. It is possible for a smaller pulse width to cause a reset.
