Description
Physical Descriptor Destination ID. 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)
001: Port 1 (GLPCI_SB)
010: Port 2 (USBC2)
011: Port 3 (ATAC)
Physical Compare BIZZARO Flag. If set, bit 8 of the address must be low for a hit on
this descriptor.
Reserved. Write as read.
Physical Memory Address Base.These bits form the matching value against which
the masked value of the physical address bits [31:12] are directly compared. If a match
is found, then a hit is declared, depending on the setting of the BIZZARO flag compara-
tor.
Physical Memory Address Mask.These bits are used to mask physical address bits
[31:12] for the purposes of this hit detection.
