Description

Bridge Features Parameter Group

G1

C_IPIFBAR_NUM

G5-G25

The set of PLB/IPIF BAR-parameters of
N = 0 to C_IPIFBAR_NUM-1 are
meaningful. When C_IPIFBAR_NUM <
6, the parameters of N =
C_IPIFBAR_NUM up to and including 5
have no effect. If C_IPIFBAR_NUM = 6,
the set of PLB/IPIF BAR-parameters of N
= 0 to 5 are all meaningful (i.e., G2-G25
are meaningful).

G2

C_IPIFBAR_0

G3

G3

G2 to G3 define range in PLB-memory
space that is responded to by this device
(IPIF BAR)

G3

C_IPIFBAR_HIGHADDR_0

G2

G2

G2 to G3 define range in PLB-memory
space that is responded to by this device
(IPIF BAR)

G4

C_IPIFBAR2PCIBAR_0

G2, G3 and

G48

Meaningful only if G48 = 0 and in this
case only high-order bits that are the
same in G2 and G3 are meaningful.

G5

C_IPIF_SPACETYPE_0

G6

C_IPIFBAR_1

G7

G1 and G7

Meaningful only if G1>1, then G6 to G7
define the range in PLB-memory space
that is responded to by this device (IPIF
BAR)

G7

C_IPIFBAR_HIGHADDR_1

G6

G1 and G6

Meaningful only if G1>1, then G6 to G7
define the range in PLB-memory space
that is responded to by this device (IPIF
BAR)

G8

C_IPIFBAR2PCIBAR_1

G1, G6, G7

and G48

Meaningful only if G48 = 0 and G1>1. In
this case only high-order bits that are the
same in G6 and G7 are meaningful.

G9

C_IPIF_SPACETYPE_1

G1

Meaningful only if G1>1

G10

C_IPIFBAR_2

G11

G1 and

G11

Meaningful only if G1>2, then G10 to
G11 define the range in PLB-memory
space that is responded to by this device
(IPIF BAR)

G11

C_IPIFBAR_HIGHADDR_2

G10

G1 and

G10

Meaningful only if G1>2, then G10 to
G11 define the range in PLB-memory
space that is responded to by this device
(IPIF BAR)
