TPS65994AE: The behavior of the TPS65994 Pin.D1(I2C_EC_IRQ) on two ports is different action.

For our X370SNx1 interrupt (I2C_EC_IRQ) measurement results:

  • Port A only shows Hi/Low action of (I2C_EC_IRQ) when a device is plugged or unplugged.
  • Port B continuously shows Hi/Low action of (I2C_EC_IRQ) after a device is inserted.

It seems there's a difference in the behavior of the two ports. Could you please advise on any modifications needed in the PD_FW? Attached are our PD_FW .PJT file and the measurement graphs. Thank you.X370_TBT5_TPS65994BH_F909p12p15_Tiger_PDv3115_20240410-1.pjt
