My customer build a custom board and let me confirm about supplying voltage to NVCC_LOW in i.MX6SX.
They don't use SD cad which is 1.8V device.
In that case, they don't have to supply 1.8V voltage to NVCC_LOW.
Am I correct ?
Can they supply 1.8V to NVCC_LOW ?
According to the P28 of IMX6SXIEC Rev. 2, 6/2016, it seems that the NVCC_LOW pin can supply 1.8V.
