Table 75. LSUn Control Register 4 (LSUn_REG4) Field Descriptions

Bit	Field	Value	Description
31-30	OUTPORTID		Not applicable for Rapid IO header. Indicates the output port number for the packet to be
			transmitted from. Specified by the CPU along with NodeID.
29-28	PRIORITY		RapidIO prio field specifying packet priority. Request packets should not be sent at a priority level of
			3 in order to avoid system deadlock. It is the responsibility of the software to assign the appropriate
			outgoing priority.
27-26	XAMBS		RapidIO xambs field specifying extended address MSB
25-24	ID_SIZE		RapidIO tt field specifying 8 or 16bit DeviceIDs
		00b	8 bit device Ids
		01b	16 bit device Ids
23-8	DESTID		RapidIO destinationID field specifying target device
7-1	Reserved		Reserved
0	INTERRUPT_RE		CPU controlled request bit used for interrupt generation. Typically used in conjunction with
	Q		Non-posted commands to alert the CPU when the requested data/status is present.
		0b	Interrupt is not requested upon completion of command
		1b	Interrupt is requested upon completion of command
