Hi Niket,

If you are using the EVM, you can go into debug mode to see the register values. However, if you are asking about for your own design, if you have a Host/EC connected to the PD controller, it will need to be read the register with the I2C address of the PD controller. Is this what your are asking for? Could you elaborate some more if I am not understanding?

Thank you,

Hari

Hi,

In our design, we connected the micro-controller with the PD controller over I2C. I want to read the highlighted field using the micro-controller. I am able to read the PD controller registers over I2C. But I don't know which register I have to read to get the highlighted field.
