Hi, i am still working on my ethernet-mcu project. I have got a Realtek 8019 ISA ethernet card and plan to connect it to a Pic mcu. I hope to operate the isa card in 8 bit mode.
The problem is I don't understand how the ISA card works. All I want to do is read data from the data ports. But there is a whole rigmarole associated with that (raising this pin high, putting that pin low..etc) before any eading can be done. Or at least that's the way it seems to me having read isa related documents and pinout diagrams on the internet.
Does someone have a simple explaination of how to get data off the isa card in 8 bit mode? What is the procedure involved to read data from the ports.
Something that does not involve wading through a ton of documents (which i have just completed with little to show for) would be much appreciated.
