TPS25751A: TPS25751A GPIO Event Mapping for Cable_Orientation_Event (Event 3)

Hori Shota

Part Number: TPS25751A

Hi team,

I have a question regarding the GPIO event configuration described in the TPS25751A TRM.

For example, if I want to assign Event 3, "Cable_Orientation_Event," to the GPIO 0 pin, should I convert the Event number "3" to binary and configure the corresponding bits as shown below?

bit	295	294	293	292	291	290	289	288
Set Value	0	0	0	0	0	0	1	1

In other words, is my understanding of the bit assignment for selecting Event 3 on GPIO 0 correct?

Best Regards,

Shota

Hello Shota,

Thank you for reaching out on E2E.

Your understanding of how to map the bit fields for GPIO event Cable_Orientation_Event is correct. I want to also note that you can send the GPIO configuration in the Customization Application Tool for the TPs25751A.

See USBCPD Application Customization Tool User Guide for a more in-depth detail on how to utilize the GUI tool and let me know if you have any follow up questions.

Bests,

Katilynn
