TPS65950/30/20 USB resume not working if DP/DM swap bit enable.

IMPACT 

The USB resume detector does not work if Data polarity changed to 0. (default is 1).

The USB System will permanently detect K on line and will never go in Suspend mode.

 

DESCRIPTION

If the IFC_CTRL[AUTORESUME] bit is enabled (default), then setting the OTHER_IFC_CTRL[DATAPOLARITY] bit to ‘0’ (default value is ‘1’) Will not allow anymore AUTO Resume detection.

 

WORKAROUND

No WA.
