8.38 Physical Request Filter Low Register

The physical request filter low set/clear register enables physical receive requests on a per-node basis, and handles the lower node IDs. When a packet is destined for the physical request context, and the node ID has been compared against the asynchronous request filter registers, then the node ID 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 asynchronous request context instead of the physical request context. See Table 8−30 for a complete description of the register contents.

DESCRIPTION

31

physReqResource31

RSC

If bit 31 is set to 1 for local bus node number 31, physical requests received by the controller from

that node are handled through the physical request context.

30

physReqResource30

RSC

If bit 30 is set to 1 for local bus node number 30, physical requests received by the controller from

that node are handled through the physical request context.

29−2

physReqResourcen

RSC

Bits 29 through 2 (physReqResourcen, where n = 29, 28, 27, …, 2) follow the same pattern as

bits 31 and 30.

1

physReqResource1

RSC

If bit 1 is set to 1 for local bus node number 1, physical requests received by the controller from

that node are handled through the physical request context.

0

physReqResource0

RSC

If bit 0 is set to 1 for local bus node number 0, physical requests received by the controller from

that node are handled through the physical request context.

8.39 Physical Upper Bound Register (Optional Register)

The physical upper bound register is an optional register and is not implemented. This register returns all 0s when read.
