How do I communicate with a EISA interface, base address 560 decimal, 6 - 16 bit registers, IRQ5

[Jmet]

Reg. 0 is PC Interrupt Status, 2 is PC Interrupt Mask, 4 is Access Address Register, 6 is Control Status, 8 is Address, 10 is Data.

Have a look on the functions palette. Under the Advanced menu there is a
section marked
'Port I/O' there are VIs for In Port and Out Port, these will probably do
what you want.

The port address is going to be the base address of your card added to the
register number.
You need to set a boolean on the Vis to indicate that you are going to be
reading and writing
words rather than bytes.
