1. Determined according to IEC Standard 61967-1, Integrated Circuits - Measurement of Electromagnetic Emissions,

150 kHz to 1 GHz Part 1: General Conditions and Definitions and IEC Standard 61967-2, Integrated Circuits -

Measurement of Electromagnetic Emissions, 150 kHz to 1 GHz Part 2: Measurement of Radiated Emissions—TEM

Cell and Wideband TEM Cell Method. Measurements were made while the microcontroller was running basic

application code. The reported emission level is the value of the maximum measured emission, rounded up to the next

whole number, from among the measured orientations in each frequency range.

3. Specified according to Annex D of IEC Standard 61967-2, Measurement of Radiated Emissions—TEM Cell and

Wideband TEM Cell Method
