1) _{The supply current is a function of the operating frequency. These parameters are tested at VDDmax and}
maximum CPU clock with all outputs disconnected and all inputs at V_IL or V_IH.
The oscillator also contributes to the total supply current. The given values refer to the worst case. For lower
oscillator frequencies the respective supply current can be reduced accordingly.
2) _{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.
