TPS65994AD: Confirm the behavior of fault_Input_Event_Port1(33) on TPS66994.

Tool/software:

Hi AE,

            I have a question for you.
       The PDFW sets fault_Input_Event_Port1(33) on P1_GPIO1.
            When the PD receives the Port1_Sink_Fault trigger low from eFuse, I want to know what behavior the PD will exhibit at this time.
            
            After triggering fault_Input_Event_Port1(33), it will assert 40h fault input GPIO, correct?
            
Best Regards

    That is correct! When we receive via the input event that there is an error event, then when reading the status register, bits 27-22 should read 0x03.

    Thank you,
