TUSB4020BI: Configuration

Part Number: TUSB4020BI

I am beginning a design with the TUSB4020BI. Can I configure it to run without an external interface? If so, how? It isn't clear to me from the data sheet.

Thanks,

Leo

Hello,
Would you elaborate on what do you mean by "external interface" ?

Hi,

I figured it out. I was wondering how to configure the chip so it was not in I2C or SMB modes. It appears from the spec that if the SCL and SDA lines are both low, the chip assumes it is not connected to an external serial interface (such as an EEPROM).

Thanks,

Leo
