GPIO pin interrupt pulse width (digital glitch filter disa‐
bled) — Synchronous path
GPIO pin interrupt pulse width (digital glitch filter disa‐
bled, analog filter enabled) — Asynchronous path
GPIO pin interrupt pulse width (digital glitch filter disa‐
bled, analog filter disabled) — Asynchronous path
External reset pulse width (digital glitch filter disabled)
