Hello,

I find there are a note for 'GP' version LQFP64 package.

In blank of UCPD, which has the number "1" .

The note is: One port with only one CC Line available(supporting limited number of use cases).

  • Is that mean only one UCPD controller( UCPD1 or UCPD2) can be use?
  • "One port with only one CC Line available" means we have to configure CC1 on one port , and CC2 on another PORT?
  • But the the pins of CC1/CC2 are fixed in the specific pins? Could you please give some suggestion and advices.

Datasheet release fixing this table is under publication process. For LQFP64, there are 2 UCPD's available, as listed in the pinout tables. Sorry about the difficulties.
