Register Structure and Format
C.1 Overview
The PCI-1752/1754/1756 is delivered with an easy-to-use 32-bit DLL
driver for user programming under the Windows 95/98/NT operating
system. We advise users to program the PCI-1752/1754/1756 using
the 32-bit DLL driver provided by Advantech to avoid the complexity
of low-level programming by register.
The most important consideration in programming the PCI-1752/
1754/1756 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-1752/1754/1756 requires 32 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+7 is the base address plus seven bytes.
