摘要： A device that can be integrated into an integrated circuit dedicated to a microprocessor, this circuit comprising a direct memory access circuit and a communications cell, the communications cell comprising a state register and a sequencer that contain first information elements, the direct memory access circuit comprising a control register that contains second information elements, wherein said device comprises action means to enable the communications cell to act directly on bits of the control register in order to make certain of the second information elements identical to certain of the first information elements. Also disclosed is a method designed to eliminate possible conflicts between a direct memory access circuit and a communications cell that are due to information elements of the same nature.
