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.
