Part Number: TUSB7340

Hi AE,    

          I would like to confirm whether the TUSB7340 supports both Modern Standby and S3 sleep states.

          If so, how should it be configured?

 

Best Regards

    The TUSB7340 supports the following power states.

    D0, D1, D2, D3hot. These D-states applies to individual devices. S-states apply t the full system. Putting he system in a s-state will chnage the D-state for the peripheral devices. 

    This is configured in the PCIe config space register 0x42

    Register 0x44 will provide the sate the TUSB7340 is in:
