Tool/software:

Hi TI teams,

I want to obtain the current status of the power button on the docking station through an alert message. However, I am encountering the following two issues:

  1. When the power button status changes, TPS65994 does not generate an interrupt.
  2. I tried polling Register 0x74 (Received Alert Data Object), but the value does not change when I press or release the power button.

The PD chip i use is TPS65994BF
The docking i use is DELL K20A001
Attached is my PJT file. Do you have any suggestions?
