Parameterize
PCI Compiler You can customize the PCI MegaCore functions by changing parameters
and specifying optional features using the Parameterize - PCI Compiler
wizard. Start the wizard by clicking Step 1: Parameterize in IP Toolbench.
These parameters allow you to customize the PCI MegaCore functions to
meet specific application requirements, such as defining read-only and
read/write PCI configuration space. The wizard is also used to enable
and parameterize optional features.
For a complete list of parameter names and descriptions found in a
generated PCI MegaCore function variation file, refer to
“Variation File
Parameters” on page 2–7 .
PCI MegaCore
Function
Settings The PCI MegaCore functions are capable of operating at clock speeds of
up to 66 MHz. Depending on the PCI device speed, the PCI 66-MHz
Capable
option is enabled or disabled on the PCI MegaCore Function
Settings page of the Parameterize - PCI Compiler wizard.
When turned on, the PCI 66-MHz Capable option sets bit 5 of the PCI
configuration space status register. For more information on the function
of this register, refer to
“Configuration Registers” on page 3–28 .
