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) These parameters describe the RSTIN
pullup, which equals a resistance of ca. 50 to 250 KΩ.
3) The maximum current may be drawn while the respective signal line remains inactive.
4) The minimum current must be drawn in order to drive the respective signal line active.
5) This specification is only valid during Reset, or during Hold- or Adapt-mode. During Hold mode Port 6 pins are
only affected, if they are used (configured) for CS
output and the open drain function is not enabled.
6) Not 100% tested, guaranteed by design characterization.
7) The supply current is a function of the operating frequency. This dependency is illustrated in the figure below.
These parameters are tested at

The oscillator also contributes to the total supply current. The given values refer to the worst case, ie. I
PDRmax
.
For lower oscillator frequencies the respective supply current can be reduced accordingly.
8) This parameter is determined mainly by the current consumed by the oscillator. This current, however, is
influenced by the external oscillator circuitry (crystal, capacitors). The values given refer to a typical circuitry
and may change in case of a not optimized external oscillator circuitry.
9) This parameter is tested including leakage currents. All inputs (including pins configured as inputs) at 0 V to
