Supply current characteristics10.3.2
The current consumption is measured as described in Pin input voltage.
Total current consumption in run mode10.3.2.1
The MCU is placed under the following conditions:
•
All I/O pins in input mode with a static value at V
DD
or V
SS
(no load)
•
All peripherals are disabled (clock stopped by peripheral clock gating registers) except if
explicitly mentioned.
Subject to general operating conditions for V
DD
and T
