read and write marks in PCI-6534 memory

[Lei Dai]

Does anyone know how the read and write marks are allocated in the memory on a 6534 card? How much space do they occupy?

Thanks

Hi,
I am not sure I understood the question properly here. If you are talking about the data transfer, in 6534, if you are transferring using DMA then it transfers in 32-byte blocks. But if the data needs to be retrieved immediately, then interrupt driver transfer needs to be made.

Please do let me know if your question have been answered or you may elaborate on the question.
