4.33 Asynchronous Request Filter Low Register
The asynchronous request filter low set/clear register is used to enable asynchronous receive requests on a per-node
basis, and handles the lower node IDs. Other than filtering different node IDs, this register behaves identically to the
asynchronous request filter high register. See Table 4–24 for a complete description of the register contents.

Table 4–24. Asynchronous Request Filter Low Register Description
BIT FIELD NAME TYPE DESCRIPTION
31 asynReqResource31 RSC
If this bit is set for local bus node number 31, then asynchronous requests received by the
TSB12LV26 from that node are accepted.
30 asynReqResource30 RSC
If this bit is set for local bus node number 30, then asynchronous requests received by the
TSB12LV26 from that node are accepted.
L L L Bits 29 through 2 follow the same pattern.
1 asynReqResource1 RSC
If this bit is set for local bus node number 1, then asynchronous requests received by the
TSB12LV26 from that node are accepted.
0 asynReqResource0 RSC
If this bit is set for local bus node number 0, then asynchronous requests received by the
TSB12LV26 from that node are accepted.
