Num
Typical values are based on characterization data at V
This is the shortest pulse that is guaranteed to be recognized as a reset pin request. Shorter pulses are not guaranteed to
override reset requests from internal sources.
When any reset is initiated, internal circuitry drives the reset pin low for about 34 bus cycles and then samples the level on
the reset pin about 38 bus cycles later to distinguish external reset requests from internal requests.
This is the minimum pulse width that is guaranteed to pass through the pin synchronization circuitry. Shorter pulses may or
may not be recognized. In stop mode, the synchronizer is bypassed so shorter pulses can be recognized in that case.
Timing is shown with respect to 20% V
