Power Curve
The following graph contains a power curve that shows power consumption at various bus frequencies.
Note:
The system clock (CLKP) can be multiplied by 2, 3, or 4 to obtain the CPU pipeline clock (PClock) speed.

Table 21 Absolute Maximum Ratings
Functional and tested operating conditions are given in Table 17. Absolute maximum ratings are stress ratings only,
and functional operation at the maximums is not guaranteed. Stresses beyond those listed may affect device reliability
or cause permanent damage to the device.
