4.16 DMA CONTROL LOGIC
The Direct Memory Access (DMA) controller is on the personal computer
CPU board, not on the CIO-DAS16/330. The CIO-DAS16/330 has the logic
on board to request a DMA transfer. In addition to the on board logic, the
DMA controller must be programmed.
Complete register specifications for the CIO-DAS16/330 DMA control
registers will be found in the previous section on the CIO-DAS16/330 control
registers. Figure 4-2. DMA Level Select Switch
