TUSB8043A: Port configuration question

Vincent Chen64988

Part Number: TUSB8043A

Hi Team,

My customer has a questions that when system and TUSB8043A is powered up, then TUSB8043A's downstream port configuration can be changed by an embedded MCU, right? This has to be via I2C, is it correct?

Thanks very much.
