(1) Parameters are characterized up to T_A = 105°C unless otherwise noted.
(2) The DCO clock wake-up time is measured from the edge of an external wake-up signal (for example, port interrupt) to the first clock
edge observable externally on a clock pin (MCLK or SMCLK).
(3) Parameter applicable only if DCOCLK is used for MCLK.
