Note:
Signals of Type “I: Constant” must either be constantly driven by the host or have a pull-up or pull-down (in
case the host is likely to tri-state the signal during power down modes). The constant drive is used to ensure
defined operation of the part and to minimize leakage current during low-power operation.
