TPS65982: Is there any method to decide which PDO (PDO#1～#7) is active when PD negotiation occured?

Part Number: TPS65982

Hi Team,

I understood Source Capabilities (PDO#1～#7) can be read from 0x32 TX Source Capabilities Register.

Is there any method to decide which PDO (PDO#1～#7) is active when PD negotiation occured?
Is there any register that should be read to achieve it?

Hello Yaita-san,

You can read register (0x34) to determine the active PDO on the device.
If you want to decide which PDO the device selects as a sink, you can configure this in the Autonegotiate Sink register (0x37).

Thank you,
Eric
