4.35 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 1 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 TSB82AA2 device. Nonlocal bus-sourced packets are not acknowledged unless bit 31 in
this register is set to 1. See Table 428 for a complete description of the register contents.

DESCRIPTION
31
asynReqAllBuses
RSC
If bit 31 is set to 1, all asynchronous requests received by the TSB82AA2 device from nonlocal bus
nodes are accepted.
30
asynReqResource62
RSC
If bit 30 is set to 1 for local bus node number 62, asynchronous requests received by the TSB82AA2
device from that node are accepted.
29
asynReqResource61
RSC
If bit 29 is set to 1 for local bus node number 61, asynchronous requests received by the TSB82AA2
device from that node are accepted.
28
asynReqResource60
RSC
If bit 28 is set to 1 for local bus node number 60, asynchronous requests received by the TSB82AA2
device from that node are accepted.
27
asynReqResource59
RSC
If bit 27 is set to 1 for local bus node number 59, asynchronous requests received by the TSB82AA2
device from that node are accepted.
26
asynReqResource58
RSC
If bit 26 is set to 1 for local bus node number 58, asynchronous requests received by the TSB82AA2
device from that node are accepted.
25
asynReqResource57
RSC
If bit 25 is set to 1 for local bus node number 57, asynchronous requests received by the TSB82AA2
device from that node are accepted.
24
asynReqResource56
RSC
If bit 24 is set to 1 for local bus node number 56, asynchronous requests received by the TSB82AA2
device from that node are accepted.
23
asynReqResource55
RSC
If bit 23 is set to 1 for local bus node number 55, asynchronous requests received by the TSB82AA2
device from that node are accepted.
22
asynReqResource54
RSC
If bit 22 is set to 1 for local bus node number 54, asynchronous requests received by the TSB82AA2
device from that node are accepted.
21
asynReqResource53
RSC
If bit 21 is set to 1 for local bus node number 53, asynchronous requests received by the TSB82AA2
device from that node are accepted.
20
asynReqResource52
RSC
If bit 20 is set to 1 for local bus node number 52, asynchronous requests received by the TSB82AA2
device from that node are accepted.
19
asynReqResource51
RSC
If bit 19 is set to 1 for local bus node number 51, asynchronous requests received by the TSB82AA2
device from that node are accepted.
