Data Memory Usage. The following are block diagrams show the flow of execution and the data resources used by the different drivers. Note that single channel drivers use the memory in the driver logic. The multiplexed drivers use a separate block of storage register for each channel. The data in the storage block is moved into and out of the memory used by the driver logic.
