I would like to use NVCC_SD1=3.3V , NVCC_SD2=1.8V, NVCC_SD3=3.3V.

Is it OK?


Because I saw the document of IMX6DQ6SDLHDG.pdf Table 4-1

NVCC_SD1 and NVCC_SD2 are in the same block..., it means it should be the same voltage level?


And I saw another document: IMX6SDLAEC.pdf   Page 13:



We know the Port #3 is independent power domain, but I don't know what's that mean " Port#1 and Port#2 are two completely independent power domains"


Does it mean " Port #1 and Port#2 are ONE independent power domain?"
