Hello Cypress Community and RajathB_01​​,

How to initiate APDO request using CCG3PA.

And As per PD Specification we need to continuously initiate request packet for every 15 Sec.

So once after initiating APDO request and successful AMS sequence, Is above sequence handled in CCG3PA FW or Do we need to handle it explicitly by initiating APDO for every 15Sec?

For reference I've attached the Screenshot.

Regards,

Pranay.

1) PPS Sink APDO is not done by default in the firmware but can be supported.

2) Currently there is no guaranteed method of avoiding src_cap.

Hi Pranay,

It is not done by default but firmware can support the feature. You can do it from pdo.c please take a look at that file.
