Hello,

TUSB422 will provide VBUS change request to MCU via I2C ,am I right?

But I cannot see the PDO/VBUS change request related register in datasheet like another PD PHY's register below?

There is no register for PDO request. It would come in as a PD message to the PD Rx register. MCU running PD stack SW would read that Rx register for the request and determine the appropriate PDO to enable.
