Table 99: Msi-X Table And Pba Structures In Bcm5718 Family - Broadcom NetXtreme/NetLink BCM5718 Series Programmer's Manual

BCM5718 Programmer's Guide
Table 99 depicts the implemented address regions of BAR4 and BAR5 in the BCM5718 family. Only two
structures are present: the MSI-X Table and the Pending Bit Array in the offsets shown in the table. Any host
accesses to the non-implemented addresses in these BARs must be gracefully handled by the controller; i.e.,
Reads return 0x0 and Writes have no effect whatsoever on the MAC.
