10.3.1 MC68340 Power Reduction at 5V
The following figures show how different variables affect typical power consumption at
5 V. Figure 10-15 shows how system activity affects current drain. Figure 10-16 shows
how voltage affects current drain at some typical operating temperatures. Figure 10-17
shows how system clock frequency affects current drain.
