Chapter 3 Electrical Characteristics
3.4
This section provides information about operating temperature range, power dissipation, and package thermal resistance. Power
dissipation on I/O pins is usually small compared to the power dissipation in on-chip logic and voltage regulator circuits, and
it is user-determined rather than being controlled by the MCU design. To take P

unusually high pin current (heavy loads), the difference between pin voltage and V

no system clock is present, or if the clock rate is very low (which would reduce overall power
consumption).
