C.1 Overview

The most important consideration in programming the PCI-1730/1733/1734 at the

the following sections is provided only for users who would like to do their own low-

C.2 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.
