TUSB2E22: TUSB2E22 application with the I2C interface.

Part Number: TUSB2E22

Tool/software:

Hi TI Specialist, 

I want to implement the I2C interface with the TUSB2E22 in my system. (Not TUSB2E221, because we won't use it due to the project budget.)

However, I can't find any relevant information about the I2C interface for the TUSB2E22 or a datasheet detailing its register functions.

Why do RSVD1 and RSVD2 need to be pulled up with a 1K ohm resistor?

Thanks for help.

Jason
