Hi, Champ,

According to C553x TRM SPRUH87C Page-450, there is a DRVVBUS bit in a Status Register (STATR), but no details about it in the document.
So, could you please let me know what status the bit shows?

Thanks in advance for your cooperation.

Best regards,

This bit enables the DRVVBUS pin intends to control the enable pin of an external charge pump that supplies VBUS. This is a feature intends for OTG function; and OTG function is not supported in C5535, thus please leave this bit as default setting.

Regards.
