Description Min. Max. Unit Notes
GPIO pin interrupt pulse width (digital glitch filter disabled)
— Synchronous path
1.5 — Bus clock
cycles

External RESET and NMI pin interrupt pulse width —
Asynchronous path
100 — ns 2
GPIO pin interrupt pulse width — Asynchronous path 16 — ns 2
Port rise and fall time — 36 ns 3
1. The greater synchronous and asynchronous timing must be met.
2. This is the shortest pulse that is guaranteed to be recognized.
3. 75 pF load
