hi

If TUSB320 is set in only UFP mode. After the host port(DFP port) is already attached with UFP (TUSB320LAI) port, can TUSB320LAI's current mode detect bit [REG0X08][BIT5:4] be automatically updated if the host or hub port changes its advertisement to a lower level or higher level as indicated over the CC pins?

For example, CCx voltage changes from: 0.61v --->1.16v---->2.04V, then REG0X08[BIT5:4] will automatically changed:00---->01---->11.
