10.2 CPM AC Timing Specifications
Table 33 and Table 34 provide the CPM input and output AC timing specifications, respectively.
NOTE: Rise/Fall Time on CPM Input Pins
It is recommended that the rise/fall time on CPM input pins should not
exceed 5 ns. This should be enforced especially on clock signals. Rise time
refers to signal transitions from 10% to 90% of VCC; fall time refers to
transitions from 90% to 10% of VCC.
