DIRECT MEMORY ACCESS (DMA)

EISA system provide seven ISA compatible DMA

channels. Any channel can be programmed to provide

EISA performance and addressing benefits to existing 8-
and 16-bit DMA devices while maintaining full ISA

compatibility.

Any DMA channel can be programmed for 8-, 16-,

32-bit DMA device size.

The function of each channel are shown below :
