3. Run (operating) I
DD
measured using external square wave clock source (f
OP
= 2MHz). All inputs 0.2V from rail. No dc
loads. Less than 100 pF on all outputs. C
L
= 20 pF on OSC2. All ports configured as inputs. OSC2 capacitance linearly
affects run I
DD
. Measured with all modules enabled.
4. Wait I
DD
measured using external square wave clock source (f
OP
= 2MHz). All inputs 0.2V from rail. No dc loads. Less
than 100 pF on all outputs. C
L
= 20 pF on OSC2. All ports configured as inputs. OSC2 capacitance linearly affects wait I
DD
.
5. Stop I
DD
measured with OSC1 grounded; no port pins sourcing current. LVI is disabled.
