The power-down sequence is recommended to be the opposite of the power-up sequence. In other words,
the same power supply constraints exist while powering off as while powering on.
4.2.3
When the i.MX50 is resuming from STOP mode, there are some special sequencing considerations. The
resume timing is determined by the following internal counters:

Resume Sequence
1) The POR_B input must be immediately asserted at power-up and remain
asserted until after the last power rail is at its working voltage.
2) No power-up sequence dependencies exist between the supplies shown
shaded in gray.
