6.2.2 PCI bus
The PCI bus is always active and the following
control signals must be pulled-up to 3.3V or 5V
through 2K2 resistors even if this bus is not con-
nected 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 6-3
shows a typical implementation.
For more information on layout constraints, go to
the place and route recommendations section.
