Appendix C Register Structure & Format
C.1 Overview
The PCI-1736UP is delivered with easy-to-use Advantech Device Driv-
ers for user programming under Windows 98/2000/XP operating systems.
We advise users to program the PCI-1736UP 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-1736UP 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-1736UP 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.
Table C.1 shows the function of each register of the PCI-1736UP or
driver and its address relative to the card's base address.
