Value for Revision ID field in the Configura-
tion Space. This value correlates to the lower
8 bits of register 08h.
Value for Class Code field in the Configura-
tion Space. This is the value of the upper 24
bits of register 08h. Class Code is further
subdivided into Base Class, Sub Class, and
Interface values. Refer to the PCI local bus
specification for valid Class codes.
Controls bits 9 and 10 in the status register,
located at the upper 16 bits of address 04h.
This parameter is used to define the decode
speed of the PCI IP core.
00 - Fast (not supported)
01 - Medium (not supported)
10 - Slow
11 - Reserved
Enable for the Capabilities Pointer. It is used
to set the enable bit for the Capabilities List in
the PCI Status register. This bit is used to
indicate if the value of the Capabilities Pointer
at location 34h is valid. This is bit 4 in the sta-
tus register.
Value for Capabilities Pointer field in the Con-
figuration Space. This is an 8-bit value
located at 34h.
Value for the Cardbus CIS Pointer field in the
Configuration Space. This is a 32-bit value
located at 28h in the Configuration Space
Settings for the CIS Pointer are beyond the
scope of this document. For more information
on setting this register, refer to the CardBus
specification.
Value for the Status field bit to enable fast
back-to-back transfers. This is bit 7 of the sta-
tus register.
Enable response to the Interrupt Acknowl-
edge PCI command.
Value for Interrupt Pin field in the Configura-
tion Space. If set, it allows the local interrupt
signal l_interruptn to appear on the PCI
Interrupt intan. If the local interrupt is not
used, it must be tied high.
Value for read-only latency timer register
Enable read only latency timer register.
Value for MIN_GRAND field in the configura-
tion space.
Value for MAX_LATENCY field in the configu-
ration space.
