1 _{This is the shortest pulse that is guaranteed to pass through the pin input filter circuitry. Shorter pulses may or may not be}
recognized.
2 _{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.
3 _{Timing is shown with respect to 20% VDD and 80% VDD levels. Temperature range –40 °C to 85 °C.}
