Hi
Please let me make clear about below two questions.
〇Question about ①
・Does this mean；
a)Supplied voltage for all IO group(NVCC_xxx) must be the same voltage?
b)Supplied voltage is depends on application requirement, but need to apply voltage at the same timing?
・Any requirement about supplied voltage timing?
〇Question about ②
・This path(from NVCC_LVDS_2P5 to DRAM_IO/RGMII_IO) can be on/off by register setting?

Hi, Igor
>what processor used in the case ?
Using I.MX6 Dual Lite.
>a). NVCC_xxx can be different.
I understood different voltage can be applied to each NVCC_xxx.
> b). timings can be found in Datasheet, "Power Up Sequence" chapter.
Yes, i know the below chapter on the datasheet, but no mentioned about NVCC_xxxx timing.
Where should I refer to understand more detail requirement about it?
>voltages which can be turned off are given in Hardware Guide, in sect."Unused Peripherls".
Which Hardware guide should i refer to?
I checked below notes, but i was not able to find that sect.
|Common Hardware Design for i.MX 6Dual/6Quad and i.MX 6Solo/6DualLite
|Hardware Development Guide for i.MX 6QuadPlus, 6Quad, 6DualPlus, 6Dual, 6DualLite, 6Solo Families of
Applications Processors
