3. Run (operating) I
DD
measured using external square wave clock source. All inputs 0.2 V 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; all inputs 0.2 V 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.
6. Maximum is highest voltage that POR is guaranteed.
7. If minimum V
DD
is not reached before the internal POR reset is released,
RST
must be driven low externally until minimum
V
DD
is reached.
