3. Run (Operating) I
DD
measured using external square wave clock source (f
OP
= 8.4 MHz). 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

. Measured with all modules enabled.
5. Stop I
DD
measured with OSC1 = V
SS
.
6. Maximum is highest voltage that POR is guaranteed.
7. Maximum is highest voltage that POR is possible.
8. 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.
