The current parameters in the table below are derived from code executing a while(1)
loop from flash, unless otherwise noted.
The IDD typical values represent the statistical mean at 25°C, and the IDD maximum
values for RUN, WAIT, VLPR, and VLPW represent data collected at 125°C junction
temperature unless otherwise noted. The maximum values represent characterized
results equivalent to the mean plus three times the standard deviation (mean + 3 sigma).

1. 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, VLPS, LLS, and VLLSx modes, the synchronizer is bypassed so shorter pulses can
be recognized in that case.
2. The greater of synchronous and asynchronous timing must be met.
3. These pins have a passive filter enabled on the inputs. This is the shortest pulse width that is guaranteed to be
recognized.
4. These pins do not have a passive filter on the inputs. This is the shortest pulse width that is guaranteed to be
