1) _{An output current above |IOXnom| may be drawn from up to three pins at the same time.}
For any group of 16 neighboring port output pins the total output current in each direction (ΣI_OL and Σ-I_OH)
must remain below 50 mA.

1) _{During Flash programming or erase operations the supply current is increased by max. 5 mA.}
2) _{The supply current is a function of the operating frequency. This dependency is illustrated in Figure 11.}
These parameters are tested at V_DDImax and maximum CPU clock frequency with all outputs disconnected and
all inputs at V_IL or V_IH.
3) _{The pad supply voltage pins (VDDP) mainly provides the current consumed by the pin output drivers. A small}
amount of current is consumed even though no outputs are driven, because the drivers’ input stages are
switched and also the Flash module draws some power from the V_DDP supply.
4) _{The total supply current in Sleep and Power-down mode is the sum of the temperature dependent leakage}
current and the frequency dependent current for RTC and main oscillator (if active).
