This parameter is characterized but not tested.
The test conditions for all I
DD
measurements in NOP execution are:
X
IN
= external square wave; all I/O pins tristated, pulled to V
SS
, EC0 = V
DD
, RESET = V
DD
; WDT disabled/enabled as specified.
Does not include current through R
ext.
The current through the resistor can be estimated by the formula; I
R
= V
DD
/2R

(mA)
Power down current is measured with the part in SLEEP mode, with all I/O pins in hi-impedance state and tied to V
DD
and V
SS
as
like measurement conditions of supply current.
