Supply current characteristics

The current consumption is a function of several parameters and factors such as the

operating voltage, ambient temperature, I/O pin loading, device software configuration,

operating frequencies, I/O pin switching rate, program location in memory and executed

binary code.

The current consumption is measured as described in Figure 11: Current consumption

measurement scheme.

All Run-mode current consumption measurements given in this section are performed with a

reduced code that gives a consumption equivalent to CoreMark code.
