Datasheet

BIT
NUMBER	BIT NAME		DESCRIPTION
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)
3	EOP_DISABLE	EOP Disable: Disables EOP generation at EOF1 when no downstream
		directed traffic is in progress.
		0	= EOP generation at EOF1 is enabled.
		1	= EOP generation at EOF1 is disabled, (normal operation). (Default)
2:1	CURRENT_SNS	Over Current Sense: Indicates whether current sensing is on a port-by-port
		basis, or ganged.
		00 = Ganged sensing (all ports together). (Default for self-power)
		01 = Individual port-by-port.
0	PORT_PWR	Port Power Switching: Indicates whether port power switching is on a port-
		by-port basis or ganged.
		0	= Ganged switching (all ports together)
		1	= Individual port-by-port switching.

BIT
NUMBER	BIT NAME		DESCRIPTION
7	DYNAMIC	Dynamic Power Enable: Controls the ability for the Hub to transition to Bus-
		Powered operation if the local power source is removed (can revert back to
		Self-Power if local power source is restored).
		0	= No Dynamic auto-switching.
		1	= Dynamic Auto-switching capable.(Default)
6	Reserved	Reserved
5:4	OC_TIMER	OverCurrent Timer: Over Current Timer delay.
		00 = 0.1ms
		01 = 2ms (Default)
		10 = 4ms
		11 = 6ms
3	COMPOUND	Compound Device: Designates if Hub is part of a compound device.
		0	= No. (Default)
		1	= Yes, Hub is part of a compound device.
2:0	Reserved	Reserved.
