A method for reducing electromagnetic emissions in an electronic device
having a multiple micro-controllers includes identifying the number of
micro-controllers installed in the electronic device. An operating
frequency range of the electronic device is determined based on the
operating frequency range of each micro-controller. A frequency spacing
for each micro-controller within the operating frequency range of the
electronic device is then calculated, and an operating frequency is
assigned to each micro-controller. The operating frequency of each
micro-controller is separated from the operating frequency of each other
micro-controller by at least the frequency spacing. Then, the operating
frequency of each micro-controller is set at the assigned operating
frequency.
