Operation modes of 8237 DMA Controller

The 8237 operates in the following modes: Rotating Priority Mode-If the RP bit of mode set register is set then the 8237 operates in rotating priority mode After each DMA cycle the priority of each channel changes Hence all channels will get equal opportunity if they are enabled and their DMA requests exist Initially CH-0 gains highest
