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 resulting voltage comes from the external circuitry.
2) This specification is only valid during reset, or interruptible power-down mode, after recep-
tion of an external interrupt signal that will wake up the CPU.
3) This specification is only valid during reset, hold or adapt-mode. Port 6 pins are only affected
if they are used for CS output and the open drain function is not enabled.
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.
This parameter is tested at VDDmax and 50 MHz CPU clock with all outputs disconnected
and all inputs at VIL or VIH with an infinite execution of NOP instruction fetched from external
memory (16-bit demux bus mode, no waitstates, no memory tri-state waitstates, normal
ALE).
8) Typical value at 25°C = 20 µA.
9) This parameter is tested including leakage currents. All inputs (including pins configured as
inputs) at 0 V to 0.1 V or at VDD – 0.1 V to VDD, VREF = 0 V, all outputs (including pins con-
figured as outputs) disconnected.
