8.35 Asynchronous Request Filter High Register
The asynchronous request filter high set/clear register enables asynchronous receive requests on a per-node
basis, and handles the upper node IDs. When a packet is destined for either the physical request context or
the ARRQ context, the source node ID is examined. If the bit corresponding to the node ID is not set to 1b in
this register, then the packet is not acknowledged and the request is not queued. The node ID comparison
is done if the source node is on the same bus as the controller. Nonlocal bus-sourced packets are not
acknowledged unless bit 31 in this register is set to 1b. See Table 827 for a complete description of the
register contents.

DESCRIPTION
31
asynReqAllBuses
RSC
If bit 31 is set to 1b, then all asynchronous requests received by the controller from nonlocal bus
nodes are accepted.
30
asynReqResource62
RSC
If bit 30 is set to 1b for local bus node number 62, then asynchronous requests received by the
controller from that node are accepted.
29
asynReqResource61
RSC
If bit 29 is set to 1b for local bus node number 61, then asynchronous requests received by the
controller from that node are accepted.
28
asynReqResource60
RSC
If bit 28 is set to 1b for local bus node number 60, then asynchronous requests received by the
controller from that node are accepted.
27
asynReqResource59
RSC
If bit 27 is set to 1b for local bus node number 59, then asynchronous requests received by the
controller from that node are accepted.
26
asynReqResource58
RSC
If bit 26 is set to 1b for local bus node number 58, then asynchronous requests received by the
controller from that node are accepted.
25
asynReqResource57
RSC
If bit 25 is set to 1b for local bus node number 57, then asynchronous requests received by the
controller from that node are accepted.
24
asynReqResource56
RSC
If bit 24 is set to 1b for local bus node number 56, then asynchronous requests received by the
controller from that node are accepted.
23
asynReqResource55
RSC
If bit 23 is set to 1b for local bus node number 55, then asynchronous requests received by the
controller from that node are accepted.
22
asynReqResource54
RSC
If bit 22 is set to 1b for local bus node number 54, then asynchronous requests received by the
controller from that node are accepted.
21
asynReqResource53
RSC
If bit 21 is set to 1b for local bus node number 53, then asynchronous requests received by the
controller from that node are accepted.
20
asynReqResource52
RSC
If bit 20 is set to 1b for local bus node number 52, then asynchronous requests received by the
controller from that node are accepted.
19
asynReqResource51
RSC
If bit 19 is set to 1b for local bus node number 51, then asynchronous requests received by the
controller from that node are accepted.
18
asynReqResource50
RSC
If bit 18 is set to 1b for local bus node number 50, then asynchronous requests received by the
controller from that node are accepted.
17
asynReqResource49
RSC
If bit 17 is set to 1b for local bus node number 49, then asynchronous requests received by the
controller from that node are accepted.
