My measurements are larger than the DS results.
yellow: wakeup key
blue: core clock
Hi @PYGC,
All specifications in Table 11 assume the clock configuration in Table 10.
Also, if you use an input active rising edge as a wakeup source, the port detects Vih_min at (0.65 x VDD), providing the input digital filter is not active.

Daniel
Is my measuring method correct? The start is VDD * 0.65, and the end is that the core clock has output.
Hello @PYGC,
What is the frequency of the core clock?
At 48MHz, one cycle is just 20ns.
The error if measurement can be significant.
What is the background of the query?
