25.1.1.10 USBx_SVID - USB Subsystem Vendor ID Register
Note:
x indicates the USB controller number.
BIOS sets the value in this register to identify the Subsystem Vendor ID. The
USB_SVID register, in combination with the USB Subsystem ID register, enables the
operating system to distinguish each subsystem from the others.
Note:
Software can write to this register only once per core well reset. Writes must be done
as a single 16-bit cycle.
