4.35 Physical Request Filter Low Register

The physical request filter low set/clear register is used to enable physical receive requests on a per-node basis and handles the lower node IDs. When a packet is destined for the physical request context and the node ID has been compared against the asynchronous request filter registers, then the node ID comparison is done again with this register. If the bit corresponding to the node ID is not set in this register, then the request is handled by the asynchronous request context instead of the physical request context. See Table 4±26 for a complete description of the register contents.

			Table 4±26. Physical Request Filter Low Register Description
BIT	FIELD NAME			TYPE							DESCRIPTION
31	physReqResource31			RSC		If this bit is set for local bus node number 31, then physical requests received by the TSB12LV26
						from that node are handled through the physical request context.
30	physReqResource30			RSC		If this bit is set for local bus node number 30, then physical requests received by the TSB12LV26
						from that node are handled through the physical request context.
						Bits 29 through 2 follow the same pattern.
1	physReqResource1			RSC		If this bit is set for local bus node number 1, then physical requests received by the TSB12LV26
						from that node are handled through the physical request context.
0	physReqResource0			RSC		If this bit is set for local bus node number 0, then physical requests received by the TSB12LV26
						from that node are handled through the physical request context.
