4.2.1.2Register 01h: Vendor ID (MSB)

BIT
NUMBER	BIT NAME	DESCRIPTION

7:0	VID_MSB	Most Significant Byte of the Vendor ID. This is a 16-bit value that uniquely
		identifies the Vendor of the user device (assigned by USB-Interface Forum).
		This field is set by the OEM using either the SMBus or EEPROM interface
		options.

4.2.1.3Register 02h: Product ID (LSB)

BIT
NUMBER	BIT NAME	DESCRIPTION

7:0	PID_LSB	Least Significant Byte of the Product ID. This is a 16-bit value that the Vendor
		can assign that uniquely identifies this particular product (assigned by OEM).
		This field is set by the OEM using either the SMBus or EEPROM interface
		options.

4.2.1.4Register 03h: Product ID (MSB)

BIT
NUMBER	BIT NAME	DESCRIPTION

7:0	PID_MSB	Most Significant Byte of the Product ID. This is a 16-bit value that the Vendor
		can assign that uniquely identifies this particular product (assigned by OEM).
		This field is set by the OEM using either the SMBus or EEPROM interface
		options.

4.2.1.5Register 04h: Device ID (LSB)

BIT
NUMBER	BIT NAME	DESCRIPTION

7:0	DID_LSB	Least Significant Byte of the Device ID. This is a 16-bit device release
		number in BCD format (assigned by OEM). This field is set by the OEM
		using either the SMBus or EEPROM interface options.

4.2.1.6Register 05h: Device ID (MSB)

BIT
NUMBER	BIT NAME	DESCRIPTION

7:0	DID_MSB	Most Significant Byte of the Device ID. This is a 16-bit device release
		number in BCD format (assigned by OEM). This field is set by the OEM
		using either the SMBus or EEPROM interface options.
