Power-up/down sequence guidelines described in datasheet.
Please let me confirm three points here.
From latest datasheet. (IMX8DXAEC Rev. 1, 5/2019)
Q1. Regarding power-up sequence. datasheet defined "a stable voltage operating within the operating range".
It means that we only care timing which over the minimum defined operating range. Is it right? I draw a timing chart based on my understanding as below. is it okay?
Q2. Regarding power-down sequence. datasheet mentioned "Supply group 0 must be turned off last, after all other supplies".
What timing the group 0 is allow to turn off? I draw a timing chart based on my understanding as below. Is it okay?
if my understanding wrong, please elaborate more detail about turn off timing.
Q3. Regarding power-up sequence. datasheet mentioned group 0 must be powered first but, other groups are allowable to power simultaneously group 0. I draw a timing chart based on my understanding as below. Is it okay?
