Notes:
1. Rise and fall time ranges are guidelines over which the I/O has been characterized.
2. T is the maximum skew within a clock forwarded group between any two signals or between any signal and its
SKEW-DIFFEDGE
forward clock, as measured at the package, with respect to different clock edges.
3. Input SU and HD times are with respect to the appropriate Clock Forward Group input clock.
4. The synchronous signals include
5. T is RSTCLK rising edge to output valid for PROCRDY. Test Load is 25 pF.
