Appendix C. Register Structure and Format
C.1 Overview
The PCI-1730/1733/1734 is delivered with easy-to-use Advantech
Device Drivers for user programming under the Windows
2000/95/98/ME/NT/XP operating system. We advise users to program
the PCI-1730/1733/1734 by using the Advantech Device Drivers
provided by Advantech to avoid the complexity of low-level
programming by register.
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.
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.
