Description
G81 C_DMA_BASEADDR
If G59 or G60=0, G83=9 or G97=0, then G81 has no
G82
G82, G83 meaning. If G83=0 and G97=1, then G81 to G82 define
and G97 the range in OPB-memory space that is responded to by
OPB PCI integral DMA register address space.
G82 C_DMA_HIGHADDR
If G59 or G60=0, G83=9 or G97=0, then G81 has no
G81
G81, G83 meaning. If G83=0 and G97=1, then G81 to G82 define
and G97 the range in OPB-memory space that is responded to by
OPB PCI integral DMA register address space.
G83 C_DMA_CHAN_TYPE
G81,
G82
G97
If G59 or G60=0, then G83 has no meaning. If G97=0,
then G83 must be set to 9.
G84 C_DMA_LENGTH_WIDTH
If G83=9 or G97=0, then G81 has no meaning.
Configuration
G85 C_INCLUDE_PCI_CONFIG
G86,
G87 and
P36
G97
If G97=0, then G85 has no meaning. If G85=1, then P36
has no internal connection to the port.
G86 C_NUM_IDSEL
G87 and
G101
G85, G87
and G97
If G85=0 or G97=0, then G86 has no meaning. If G85=1
and G97=1, then G86 sets the number of devices
supported in configuration operations. Must be
sufficiently large to include the address bit defined by
G87. If G101=1, then G86 restricts the allowed values
that are meaningful in the Device Number Register.
G87
C_BRIDGE_IDSEL_
ADDR_BIT
G85, G86, If G85 or G97=0 or G101=1, then G87 has no meaning.
G86
G97 and If G85 and G97=1 and G101=0, then G87 must be
G101 consistent with the setting of G86.
IPIF Parameters Group
G88 C_DEV_BLK_ID
G59, G60
and G96
If G59, G60, or G96=0, then G88 has no meaning.
G89 C_DEV_MIR_ENABLE
G59, G60
and G96
If G59, G60, or G96=0, then G89 has no meaning.
G90 C_INCLUDE_DEV_ISC
G59, G60
and G95
If G59, G60, or G95=0, then G90 has no meaning.
G91
C_INCLUDE_DEV_
PENCODER
G59, G60
and G95
If G59, G60, or G95=0, then G91 has no meaning.
G92 C_OPB_AWIDTH
Only 1 setting
G93 C_OPB_DWIDTH
Only 1 setting
G94 C_FAMILY
G59,
G60,
G104,
G105,
G106
Limits maximum of G59 and G60. If G94 ≠ Virtex-4, then
G104-G106 have no meaning.
G95
C_INCLUDE_INTR_
MODULE
G59, G60
and G97
If G59, G60 or G97=0, then G95 must be set to 0.
G96
C_INCLUDE_
RESET_MODULE
G59 and
G60
If G59, G60 or G97=0, then G96 must be set to 0.
