TUSB320: Difference between CURRENT_MODE_ADVERTISE and CURRENT_MODE_DETECT

Hi TI,

What is the difference between CURRENT_MODE_ADVERTISE and CURRENT_MODE_DETECT? 

I tried to read the register value of 0x08. It is 0x30. 

It means CURRENT_MODE_ADVERTISE is 00 which is default. 

However CURRENT_MODE_DETECT is 11 which is high.

Seems like these two value conflict with each other.

I am using TUSB320 as an UFP. Does that mean I do not need to be worry about CURRENT_MODE_ADVERTISE because only DFP side will advertise?

Thanks!

cheers
