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.
