6.3.4. PCI BUS
The PCI bus is always active and the following
control signals must be pulled-up to 3.3V or 5V
through 8K2 resistors even if this bus is not
connected to an external device: FRAME#,
TRDY#, IRDY#, STOP#, DEVSEL#, LOCK#,
SERR#, PERR#, PCI_REQ#[2:0].
PCI_CLKO must be connected to PCI_CLKI
through a 10 to 33 Ohms resistor. Figure 6-8
shows a typical implementation.
For more information on layout constraints, go to
the place and route recommendations section.
In the case of higher clock load it is recommended
to use a zero-delay clock buffer as described in
Figure 6-9. This approach is also recommended
when
implementing
the
delay
on
PCICLKI
according to the PCI section of the Electrical
Specifications chapter.
