The maximum is only a guideline to ensure a low current consumption during the change in
VDD.
The transition need not be monotonic, providing that the notRST pin is forced low during
the whole period while the main VDD voltage is not within limits set in the DC operating
conditions.
Parameter
Rise time of VDD during power up (measured
between 0.3 V and 2.7 V).
Fall time of VDD during power down (measured
between 2.7 V and 0.3 V).
