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
.
4. Wait I

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. The 8kHz clock is from a 32kHz clock input at OSC1, for the driving the RTC.
6. LCD driver configured for low current mode.
7. Maximum is highest voltage that POR is guaranteed.
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.
