Characteristic Definition
*When RESET# is active the BIT-CLK and SDATA-IN must be floating by internal pull low
100K resistors. So the ac-link signals are driven by another AC’97 on CNR board. This
requirement is not mentioned in AC’97 specification rev2.1, please refer CNR (Communication
Network Riser) specification rev1.0 page23~25 to get detail information.
