8.36 Asynchronous Request Filter Low Register
The asynchronous request filter low set/clear register enables 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 8−28 for a complete description of the register contents.

Table 8−28. Asynchronous Request Filter Low Register Description
BIT FIELD NAME TYPE DESCRIPTION
31 asynReqResource31 RSC If bit 31 is set to 1 for local bus node number 31, asynchronous requests received by the controller
from that node are accepted.
30 asynReqResource30 RSC If bit 30 is set to 1 for local bus node number 30, asynchronous requests received by the controller
from that node are accepted.
29−2 asynReqResourcen RSC Bits 29 through 2 (asynReqResourcen, where n = 29, 28, 27, … , 2) follow the same pattern as
bits 31 and 30.
1 asynReqResource1 RSC If bit 1 is set to 1 for local bus node number 1, asynchronous requests received by the controller
from that node are accepted.
0 asynReqResource0 RSC If bit 0 is set to 1 for local bus node number 0, asynchronous requests received by the controller
from that node are accepted.
