1. In conventional PCI switching, current characteristics for X_REQ# and X_GNT# are permitted to be one half
of that specified here; i.e., half size drivers may be used on these signals. This specification does not apply to
CLK and RSTIN# which are system outputs. “Switching Current High” specifications are not relevant to
X_SERR# which is an open drain output.
2. This parameter is to be interpreted as the cumulative edge rate across the specified range rather than the
instantaneous rate at any point within the transition range. For more details on slew rate measurement
conditions please refer to the PCI-X Electrical and Mechanical Addendum to the PCI Local Bus Specification,
