1) The supply current is a function of the operating frequency. This dependency is illustrated in Figure 10.

These parameters are tested at

VDDmax and maximum CPU clock with all outputs disconnected and all inputs

VIL or VIH.

2) This parameter is determined mainly by the current consumed by the oscillator (see Figure 8). 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.

3) 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 configured as outputs) disconnected.
