		(Sheet 2 of 2)

Bits		Type	Reset	Description

				PCI-X Detected Target Abort (optional in specification): The 41210 sets this bit when it
2		RWCS	0b	is the master of a request transaction on the PCI bus and it receives a target abort. The
2		RWCS	0b	41210 logs the header for that transaction. This bit is also set when the bridge receives a
				PCI-X Split Completion Message with Target Abort Status. The header log under this
				condition is the command, address, and attribute portion of the Split Completion Message.

				PCI-X Detected Split Completion Master Abort: The 41210 sets this bit when a split
1		RWCS	0b	completion sent by the 41210 on the PCI-X bus master-aborts. The 41210 logs the header
				of the split completion.

				PCI-X Detected Split Completion Target Abort (optional in specification): The 41210
0		RWCS	0b	sets this bit when a split completion sent by the 41210 on the PCI-X bus target-aborts. The
				41210 logs the header.
