1) This specification is not valid for outputs which are switched to open drain mode. In this case
2) This specification is only valid during reset, or interruptible power-down mode, after recep-
3) This specification is only valid during reset, hold or adapt-mode. Port 6 pins are only affected
4) The maximum current may be drawn while the signal line remains inactive.
5) The minimum current must be drawn in order to drive the signal line active.
6) Not 100% tested, guaranteed by design characterization.
7) Supply current is a function of operating frequency as illustrated in Figure 10 on page 44.
8) Typical value at 25°C = 20 µA.
9) This parameter is tested including leakage currents. All inputs (including pins configured as
