Power-down Sequence
To ensure that the device does not operate outside the operating conditions defined in Section 4.1 “Power
Supplies”, it is good practice to first place the device in reset state before removing its power supplies. No specific
sequencing is required with respect to its supply channels as long as the NRST line is held active during the
power-down phase.
