1 _{Typical values are based on characterization data at VDD = 5.0 V, 25 °C unless otherwise stated.}
2 _{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.
3 _{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.
4 _{Timing is shown with respect to 20% VDD and 80% VDD levels. Temperature range –40 °C to 105 °C.}
