Overview

The most important consideration in programming the PCI-1730/1733/1734 at the
register level is to understand the function of the card's registers. The information in
the following sections is provided only for users who would like to do their own low-
level programming.

I/O Port Address Map

The PCI-1730/1733/1734 requires 16 consecutive addresses in the PC's I/O space.
The address of each register is specified as an offset from the card's base address.
For example, BASE+0 is the card's base address and BASE+6 is the base address
plus six bytes. The table C-1 shows the function of each register of the PCI-1730/
1733/1734 or driver and its address relative to the card's base address.
