... FAS368M supports internal multimode LVD and single-ended (SE) transceivers, which allow the chip to support LVD and SE operations in initiator and target roles. The FAS368M is a single-chip controller for use in host and peripheral applications. To ensure firmware compatibility and provide FAS366U customers a seamless upgrade path, the FAS368M uses the same SCSI core, foundry, and process as the FAS366U ...

... The DREQ signal initiates DMA transfers and runs asynchronous to the user’s clock. For read operations, DACK acts as a chip select to enable the FAS368M drivers onto the DMA bus. The chip select role of DACK helps support the burst timing of fast DMA mode. DACK selects the FAS368M after DREQ is asserted and is removed either after DREQ is deasserted or when the DMA transfer is paused ...
