3. IDD measured with port B pullup devices disabled.
4. Run (operating) IDD measured using external square wave clock source (fOSC = 4.2 MHz). All inputs 0.2 V from rail. No dc
loads. Less than 50 pF on all outputs. CL = 20 pF on OSC2. OSC2 capacitance linearly affects run IDD.
5. Wait IDD measured using external square wave clock source (fOSC = 4.2 MHz). All inputs 0.2 V from rail. No dc loads. Less
than 50 pF on all outputs. CL = 20 pF on OSC2. VIL = 0.2 V, VIH = VDD – 0.2 V. All ports configured as inputs. SPI and SCI
disabled. If SPI and SCI enabled, add 10% current draw. OSC2 capacitance linearly affects wait IDD.
6. Stop IDD measured with OSC1 = VDD. All ports configured as inputs. VIL = 0.2 V, VIH = VDD – 0.2 V.
