All peripheral clocks are disabled upon reset. Writing to/reading
from peripheral registers is possible only after the peripheral clocks
are turned on.
This number represents the current drawn by the digital portion of
the ADC module. Turning off the clock to the ADC module results in
the elimination of the current drawn by the analog portion of the
ADC (I
DDA18
) as well.

NOTE
The baseline I
DD
current (current when the core is executing a dummy loop with no
peripherals enabled) is 110 mA, typical. To arrive at the I
current for a given application,
the current-drawn by the peripherals (enabled by that application) must be added to the
baseline I
DD
current.
