The “#” symbol at the end of a signal name indicates that the active (asserted) state occurs when 
the signal is at a low voltage level. When “#” is not present after the signal name, the signal is 
asserted when at the high voltage level. The following notations are used to describe the signal 
type:

I:

Input pin

O:

Output pin

OD:

Open-drain Output pin

I/O:

Bidirectional Input/Output pin

I/OD:

Bidirectional Input/Open-drain Output pin

incorporates On-Die Termination (ODT) for most of the PCI interface signals. ODT eliminates the 
need for the system designer to incorporate external pull-up resistors in the design.
