4.37 Physical Request Filter High Register
The physical request filter high set/clear register enables 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 to 1 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 TSB82AA2 device. Nonlocal
bus sourced packets are not acknowledged unless bit 31 in this register is set to 1. See Table 430 for a complete
description of the register contents.

DESCRIPTION
31
physReqAllBusses
RSC
If bit 31 is set to 1, all physical requests received by the TSB82AA2 device from non-local bus
nodes are accepted. Bit 31 is not cleared by a PCI_RST.
30
physReqResource62
RSC
If bit 30 is set to 1 for local bus node number 62, physical requests received by the TSB82AA2
device from that node are handled through the physical request context.
29
physReqResource61
RSC
If bit 29 is set to 1 for local bus node number 61, physical requests received by the TSB82AA2
device from that node are handled through the physical request context.
28
physReqResource60
RSC
If bit 28 is set to 1 for local bus node number 60, physical requests received by the TSB82AA2
device from that node are handled through the physical request context.
27
physReqResource59
RSC
If bit 27 is set to 1 for local bus node number 59, physical requests received by the TSB82AA2
device from that node are handled through the physical request context.
26
physReqResource58
RSC
If bit 26 is set to 1 for local bus node number 58, physical requests received by the TSB82AA2
device from that node are handled through the physical request context.
25
physReqResource57
RSC
If bit 25 is set to 1 for local bus node number 57, physical requests received by the TSB82AA2
device from that node are handled through the physical request context.
24
physReqResource56
RSC
If bit 24 is set to 1 for local bus node number 56, physical requests received by the TSB82AA2
device from that node are handled through the physical request context.
23
physReqResource55
RSC
If bit 23 is set to 1 for local bus node number 55, physical requests received by the TSB82AA2
device from that node are handled through the physical request context.
22
physReqResource54
RSC
If bit 22 is set to 1 for local bus node number 54, physical requests received by the TSB82AA2
device from that node are handled through the physical request context.
21
physReqResource53
RSC
If bit 21 is set to 1 for local bus node number 53, physical requests received by the TSB82AA2
device from that node are handled through the physical request context.
20
physReqResource52
RSC
If bit 20 is set to 1 for local bus node number 52, physical requests received by the TSB82AA2
device from that node are handled through the physical request context.
