TUSB4020BI: default setting

Part Number: TUSB4020BI


Hi 

Our customer would like to know the default setting.

This device has some configuration register. If we want to change the register , we can change the setting by I2C or EEPROM after power up.

However if we do not need to change the register setting, can we use this device without changing the register? 

If it is so, can we leave tSDA/SMBDAT pin open? (On the datasheet it is mentioned as below.)

Please let me know if you have any concerns with our configuration(case of use with default setting).

Regards,
