8.37 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 PCI7x21/PCI7x11 controller.
Nonlocal bus-sourced packets are not acknowledged unless bit 31 in this register is set to 1. See Table 8−29 for a
complete description of the register contents.

Table 8−29. Physical Request Filter High Register Description
BIT FIELD NAME TYPE DESCRIPTION
31 physReqAllBusses RSC If bit 31 is set to 1, all asynchronous requests received by the controller from nonlocal bus nodes
are accepted. Bit 31 is not cleared by a PRST.
30 physReqResource62 RSC If bit 30 is set to 1 for local bus node number 62, physical requests received by the controller
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 controller
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 controller
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 controller
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 controller
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 controller
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 controller
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 controller
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 controller
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 controller
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 controller
from that node are handled through the physical request context.
19 physReqResource51 RSC If bit 19 is set to 1 for local bus node number 51, physical requests received by the controller
from that node are handled through the physical request context.
