I am developing an application using CCG3PA that requires dynamically updating the configuration table during operation. In the documentations, the only way of changing the configuration table is through the PC software. Is there a way to have it updated by the firmware during application?

Hi Eric,

Based on the firmware capabilities of CCGx, CCG3/4/5 can change the configuration table through firmware and the configuration table will be effective when power off and power up or reset after update. For CCG3PA, I could like to recommend you GET_SINK_CAP and acknowledge all of SINK_CAP and then enable SOURCE_CAP as per SINK_CAP.

Best Regards,

Lisa

Hi!

You can also change to PODs using the I2C interface at runtime if you are not eager to make a custom firmware.

Cheers
