Appendix A Electrical Characteristics
A.12 AC Characteristics
This section describes ac timing characteristics for each peripheral system.

Typical data was characterized at 5.0 V, 25°C unless otherwise stated.
This is the shortest pulse that is guaranteed to be recognized as a RESET pin or pin interrupt request. Shorter pulses are not
guaranteed to override reset requests from internal sources.
