Hi team,

My customer ask me about Autonegotiate Sink (0x37), but I don't use it before.

Could you give me an example how to use Autonegotiate Sink (0x37) in GUI setting.

I don't very understand what's the function of RDO power parameter and RDO current parameter.

I also read the TRM, but they don't explain more detail. could you give me an example let me more understand, thanks.

Hi Jason,

The purpose of this register is to select an appropriate PDO when the PD power role is SNK.

The power field is to set a minimum power threshold for the contract. This can be set manually or by auto computation. If the PD is set to autocompute this power, the minimum threshold will be the maximum power computed from the SNK Capabilities settings.
