Hello. I have a question about USB_nOTGSC register in i.MX6DQ.
Refer to AVVIS and AVV bits in USB_nOTGSC register.
A VBus Valid Interrupt Status - Read/Write to Clear.
This bit is set when VBus has either risen above or fallen below the VBus valid threshold on an A device.
Software must write a one to clear this bit.
A VBus Valid - Read Only.
Indicates VBus is above the A VBus valid threshold.
I want to know the condition of set these bits.
Could you tell me about "valid threshold"?
