Note 1:
I
DOZE
is primarily a function of the operating voltage and frequency. Other factors, such as I/O pin loading
and switching rate, oscillator type, internal code execution pattern and temperature, also have an impact
on the current consumption. The test conditions for all I
on the current consumption. The test conditions for all I
DOZE
measurements are as follows:
• Oscillator is configured in EC mode and external clock is active, OSC1 is driven with external square
wave from rail-to-rail (EC clock overshoot/undershoot < 250 mV required)
• CLKO is configured as an I/O input pin in the Configuration Word
• All I/O pins are configured as inputs and pulled to V
• All I/O pins are configured as inputs and pulled to V
