Hi, TI team,

We're designing notebook using TI PDC.
And we've noticed this difference, when we attach our product with some of PD monitor.
- TPS65987DDJ: DFP_D = C
- TPS65994AD/AE: DFP_D = D

Why this difference does occur ? And also, which behavior is correct?
We'd appreciate if you tell us for the detail.
