Dear All,

 

Hello. I have a question about USB_nOTGSC register in i.MX6DQ.

Refer to AVVIS and AVV bits in USB_nOTGSC register.

 

"AVVIS"

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.

 

"AVV"

A VBus Valid - Read Only.

Indicates VBus is above the A VBus valid threshold.

 

[Question]

I want to know the condition of set these bits.

Could you tell me about "valid threshold"?

 

Best Regards,
Keita
