Option 2

•

If PCI arbiter is disabled during POR,

•

All AD pins will be in the input state. Therefore, all ADs pins need to be grouped together and tied

to OVDD through a single (or multiple) 10-kΩ resistor(s).

•

All PCI control pins can be grouped together and tied to OVDD through a single 10-kΩ resistor.

21.12 Guideline for LBIU Termination

If the LBIU parity pins are not used, the following list shows the termination recommendation:

•

For LDP[0:3]: tie them to ground or the power supply rail via a 4.7-k

Ω resistor.

•

For LPBSE: tie it to the power supply rail via a 4.7-k

Ω resistor (pull-up resistor).
