TUSB322I: DRP toggle or Accessory toggle happens in UFP-only mode??

Part Number: TUSB322I

A customer would like to configure TUSB322I as UFP-only mode with UFP accessory support disabled. But it shows CC toggles.

EN_N low, I2C mode, Vdd active.
Max time from EN_N low and Vdd active to I2C access available is 100ms.
So the external MCU wait for 100ms since TUSB322I is powered on.
Then it initializes the register via I2C as follows.
[1] ADDRESS 0x0A = 0x01 ( Disable termination )
[2] ADDRESS 0x0A = 0x11 ( UFP mode )
[3] ADDRESS 0x09 = 0x21 ( Disable UFP accessory support )
[4] ADDRESS 0x0A = 0x10 ( Enable termination )

I think that the procedure is correct. My only concern is the duration between register accesses.
Do you have recommended duration between register accesses?

Regards
