Explanation: While any instruction is being executed, a micro controller first fetches the instruction (captures its operand and operator). After capturing it converts these operand and operators into their corresponding hex codes. Hence after this, instruction can be executed as now it is in the form of 0’s and 1’s (the format understood by a micro controller).
