Other Parts Discussed in Thread: HD3SS460, TPS65981
Hello Sir/Mam,
We are using TPS65981EVM in our application for sink mode. Connecting USB Type C cable between Mobile and TPS65981EVM USB Type C port. I want to control the MUX HD3SS460 via the GPIOs from the TPS65981.
Currently we are just setting up the TPS65981EVM below pins GPIO using GUI 6.1.2 and checking GPIO status while changing orientation.

Plug Event |
GPIO0 |
|
Cable orientation |
GPIO2 |
|
AMSEL |
GPIO3 |
As per our application we set GPIO in GUI and Flash binary but we didn't get changes while Change Cable Orientation. Also tried internal Pullup configuration all GPIO’s but still showing both orientations logic level “0”.

Please let me know if any point is missed at our side.
