Each box represents some processing that has to be performed by the CPU for the peripheral to operate.</p> <p>In between the boxes the peripheral will run on its own, and the CPU is free to go into sleep (system ON), or to do other tasks.</p> <p>The length of the boxes is not exact, it is just a coarse representation of how much processing each step involves, but the number of processing steps (boxes) is usually accurate.</p> <p>Best regards<br /> Torbjørn</p><div style="clear:both;"></div>
