The test conditions for all I
enabled/disabled as specified. The power-down/shutdown current in SLEEP mode does not depend on the oscillator frequency. Power-
down current is measured with the part in SLEEP mode, with all I/O pins in hi-impedance state and tied to V
the additional current consumed when the WDT is enabled. This current should be added to the base I

The supply current is mainly 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.
