Hi all
Please teach me the register setting and voltage supply of NVCC_USB_H.
I understand that NVCC_USB_H can be connected to I2C power rail from following thread.
I guess it's same as case of using GPIO.
Question, i.MX6SoloX power design
I want to use "USB_H_DATA" and "USB_H_STROBE" pin as 1.8 V level GPIO.
According to the table 10 of IMX6SXCEC, the NVCC_USB_H pin specification is as below.
Do I need to set the register when I use "USB_H_DATA" and "USB_H_STROBE" pin as 1.8 V level GPIO ?

this table is correct, you can set register as table shows.
I know the table is correct.
My question is do I need to set the DDR_SEL field of IOMUXC_SW_PAD_CTL_PAD_USB_H_DATA register to "11” when I use the pin as a 1.8V GPIO ?
I can't understand that why the pins related to the DDR.
