5.2.3.2EEPROM Offset 3:2(h) - Product ID

BIT
NUMBER	BIT NAME	DESCRIPTION
15:8	PID_MSB	Most Significant Byte of the Product ID.
7:0	PID_LSB	Least Significant Byte of the Product ID.

5.2.3.3EEPROM Offset 5:4(h) - Device ID

BIT
NUMBER	BIT NAME	DESCRIPTION
15:8	DID_MSB	Most Significant Byte of the Device ID.
7:0	DID_LSB	Least Significant Byte of the Device ID.

5.2.3.4EEPROM Offset 6(h) - CONFIG_BYTE_1

BIT
NUMBER	BIT NAME		DESCRIPTION
7	SELF_BUS_PWR	Self or Bus Power: Selects between Self- and Bus-Powered operation.
		0	= Bus-Powered operation. (BUS Default)
		1	= Self-Powered operation. (SELF Default)
		Note: If Dynamic Power Switching is enabled, this bit is ignored and the
		SELF_PWR pin is used to determine if the hub is operating from self or bus
		power.
6	PORT_IND	Port Indicator Support: Indicates implementation of LED indicators
		0	= No LED indicators.
		1	= LED indicators.
5	HS_DISABLE	High Speed Disable: Disables the capability to attach as either a High/Full-
		speed device, and forces attachment as Full-speed only i.e. (no High-Speed
		support).
		0	= High-/Full-Speed. (Default)
		1	= Full-Speed-Only (High-Speed disabled!)
4	MTT_ENABLE	Multi-TT enable: Enables one transaction translator per port operation.
		0	= single TT for all ports.
		1	= one TT per port (multiple TT’s supported)
