#99059 - 52 DMA Responding to: ???'s previous message |
Russell Bull said:
The 8051 architecture doesn't dictate whether the hardware does DMA! Its just that most 8051's don't have DMA facilities. I suppose the cunning thing is that with its Harvard architecture and internal resources, a '52 can still do useful work, whilst you guarantee no XRAM access, and let DMA take place. The 8052-BASIC firmware actually did that, if you asserted a certain pin, it stayed entirely in chip. Steve |
