Abstract
Each microcontroller realizing the code saved in a program memory emits electromagnetic disturbances, both conducted that propagate through lines connected to the processor and radiated in the form of electromagnetic field. All of these undesirable signals emitted by the processor can be measured, received and interpreted by the appropriate methods. However, this subject requires a precise measurement and understanding of processes occurring inside the microprocessor during realization of the sequential instructions. The presented results of the influence of parameters such as data bus state, instruction argument, the result of operation on the voltage waveform on the power supply lines of microprocessor, enable to understand the processes occurring during the realization of following instructions by microprocessor unit.
