* init the sts flag to 0 (missed)
* Set PORTCS_STS only if VUSB_HS_PHY_TYPE > 1
otherwise the register is ReadOnly
* Set/Reset correct BIT(28)/BIT(29) for STS

The coding style is still wrong at places...

No need for outer (). And it's preferred that an operator is left at the end of a first line, not starts the continuation line.
