Appendix A Electrical Characteristics
A.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

system clock is present, or if the clock rate is very low (which would reduce overall power
consumption).
