Question about DMA

[Benoit.LEBLANC at fr.thalesgroup.com]

Mister,

I read your article about DMA since I have to use a 8237 DMA controller.
I have a question and can't find (or understand) the answer:

How does the peripheral asking for a DMA transfer specify to the CPU if it
asks for a memory/IO read/write cycle?

Thank you very much for your help,
Regards,
