Notes 1. This specification is not valid for outputs which are switched to open drain mode. In this case the respective output will float and the

voltage results from the external circuitry.

2. The maximum current may be drawn while the respective signal line remains inactive.

3. The minimum current must be drawn in order to drive the respective signal line active.

4. This specification is only valid during Reset, or during Hold- or Adapt-mode. Port 6 pins are only affected if they are used as CSx

output and the open drain function is not enabled.

5. Partially tested, guaranteed by design characterization.

6. The supply current is a function of the operating frequency. This dependency is illustr ated in the figure below. These parameters

are tested at VDDmax and 20MHz CPU clock with all outputs disconnected and all inputs at VIL or VIH.

7. This parameter is tested including leakage currents. All inputs (including pins configured as inputs) at 0V to 0.1V or at VDD – 0.1V

to VDD,VREF = 0V, all outputs (including pins configured as outputs) disconnected.

8. Overload conditions occur if the standard operating conditions are exceeded, i.e. the voltage on any pin exceeds the specified

range (i.e. VOV > VDD+0.5V or VOV <VSS-0.5V). The absolute sum of input overload currents on all port pins may not exceed 50mA

(see Figure 8).
