General Purpose DMA Interface

This user's manual provides comprehensive information on the DRV11-B general-purpose direct memory access (DMA) interface designed for LSI-11 systems. It covers installation procedures, hardware configuration (including device and interrupt vector address selection), and detailed register descriptions (WCR, BAR, CSR, and data buffers). Additionally, the manual explains basic operations, including DMA data transfer modes (DATO/DATOB and DATI/DATIO), burst mode operation, interrupt handling, and programming considerations, along with timing diagrams for interface signal synchronization.
