TPS65987D: PD GUI Config Issue

Part Number: TPS65987D
Other Parts Discussed in Thread: TUSB546A-DCI, TPS65987

Hi team,

There are two questions about the GUI config:

Questions 1:

There are port0 and port1 in I2C master config, what is the difference between the two? How to config two slaves by I2C?

Questions 2:

As shown in the datasheet below, after power-on (VCC from 0 V to 3.3 V), TUSB546A-DCI defaults to USB 3.1 mode. The USB PD controller must switch the TUSB546A- DCI moved out of USB 3.1 mode.

The customer only has DP mode. How to set GPIO in TPS65987?

Thanks for your support.

BR，

Comi

    This is correct. In that register you would set the i2c slave devices.

    You can configure I2C master events based on either common events or port specific events in register 0x62.

    They can use the DP events here to control it.

    Thank you,
