Clock Input Timing
NOTE
AVDDn (1.0 V) is estimated to consume 0.05 W (under normal operating
conditions and ambient temperature).

Clock Input Timing
This section provides the clock input DC and AC electrical characteristics for the MPC8323E.
NOTE
The rise/fall time on QUICC Engine 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.
