4.34 Physical Request Filter High Register

The physical request filter high set/clear register is used to enable physical receive requests on a per-node basis and handles the upper node IDs. When a packet is destined for the physical request context and the node ID has been compared against the ARRQ registers, then the 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 ARRQ context instead of the physical request context. The node ID comparison is done if the source node is on the same bus as the TSB42AD2. Nonlocal bus sourced packets are not acknowledged unless bit 31 in this register is set. See Table 4±25 for a complete description of the register contents.

		Table 4±25. Physical Request Filter High Register Description
BIT	FIELD NAME		TYPE	DESCRIPTION
31	physReqAllBusses		RSC	If this bit is set, then all physical requests received by the TSB12LV26 from non-local bus nodes
				are accepted.
30	physReqResource62		RSC	If this bit is set for local bus node number 62, then physical requests received by the TSB12LV26
				from that node are handled through the physical request context.
29	physReqResource61		RSC	If this bit is set for local bus node number 61, then physical requests received by the TSB12LV26
				from that node are handled through the physical request context.
28	physReqResource60		RSC	If this bit is set for local bus node number 60, then physical requests received by the TSB12LV26
				from that node are handled through the physical request context.
27	physReqResource59		RSC	If this bit is set for local bus node number 59, then physical requests received by the TSB12LV26
				from that node are handled through the physical request context.
26	physReqResource58		RSC	If this bit is set for local bus node number 58, then physical requests received by the TSB12LV26
				from that node are handled through the physical request context.
25	physReqResource57		RSC	If this bit is set for local bus node number 57, then physical requests received by the TSB12LV26
				from that node are handled through the physical request context.
24	physReqResource56		RSC	If this bit is set for local bus node number 56, then physical requests received by the TSB12LV26
				from that node are handled through the physical request context.
23	physReqResource55		RSC	If this bit is set for local bus node number 55, then physical requests received by the TSB12LV26
				from that node are handled through the physical request context.
22	physReqResource54		RSC	If this bit is set for local bus node number 54, then physical requests received by the TSB12LV26
				from that node are handled through the physical request context.
21	physReqResource53		RSC	If this bit is set for local bus node number 53, then physical requests received by the TSB12LV26
				from that node are handled through the physical request context.
20	physReqResource52		RSC	If this bit is set for local bus node number 52, then physical requests received by the TSB12LV26
				from that node are handled through the physical request context.
