Table 8-6 Vendor ID MSB Register
BitFieldTypeResetDescription
7:0vendorIdMsbR/W4hVendor ID MSB. Most significant byte of the unique vendor ID assigned by the USB-IF; the default value of this register is 04h representing the MSB of the TI Vendor ID 0451h. The value may be overwritten to indicate a customer vendor ID.
This field is read/write unless the OTP ROM VID and OTP ROM PID values are non-zero. If both values are non-zero, the value when reading this register shall reflect the OTP ROM value.
