3. Run mode IDD is measured using external square wave clock source; all inputs 0.2 V from rail; no dc loads; less than 50 pF
on all outputs; CL = 20 pF on OSC2.
4. Wait mode IDD: only timer system active. Wait mode is affected linearly by OSC2 capacitance. Wait mode is measured
with all ports configured as inputs; VIL = 0.2 V; VIH = VDD – 0.2 V. Wait mode IDD is measured using external square wave
clock source; all inputs 0.2 V from rail; no dc loads; less than 50 pF on all outputs; CL = 20 pF on OSC2.
5. Stop mode IDD is measured with OSC1 = VSS. Stop mode IDD is measured with all ports configured as inputs; VIL = 0.2 V;
VIH = VDD – 0.2 V.
