WAKE-UP MANAGEMENT TIMING TABLE
(V
Note: The value in the left hand column shows the formula used to calculate the timing minimum or maximum from the oscillator clock period.
The value in the right hand two columns show the timing minimum and maximum for an internal clock at 25MHz (INTCLK).
The given data are related to Wake-up Management Unit used in External Interrupt mode.
Measurement points are taken with reference to V
(1) Formula guaranteed by design.
Legend:
Tck = INTCLK period = OSCIN period when OSCIN is not divided by 2;
