Hi,

Anyone knows about the IOWR function declaration/definition?

I need to know how the IDE drivers the data to pins of my component in SoPC.

For example, if I have a LED_PIO with widht 8 bits, I just write IOWR (LED_PIO_BASE, 0, DATA) and I think the DATA will be sent to pins. But, if I have a component as DM9000A Ethernet controller, with 38 pins, where some are data and some are control, how I can set the correct pins to write a word?
