IDID_BM

I/O Descriptor Destination ID. These bits define which port to route the request to if it is

a hit based on the other settings in this register.

000: Port 0 (GLIU)

100: Port 4 (DD)

001: Port 1 (GLPCI_SB)

101: Port 5 (ACC)

010: Port 2 (USBC2)

110: Port 6 (USBC1)

011: Port 3 (ATAC)

111: Port 7 (GLCP)

ICMP_BIZ_BM

Compare BIZZARO Flag.

0: Consider only transactions whose BIZZARO flag is low as a potentially valid address

hit. A low BIZZARO flag indicates a normal transaction cycle such as a memory or

I/O.

1: Consider only transactions whose BIZZARO flag is high as a potentially valid address

hit. A high BIZZARO flag indicates a ‘special’ transaction, such as a PCI Shutdown or

Halt cycle.
