D. Register Structure and Format
D.1 Overview
The PCI-1712/1712L is delivered with an easy-to-use 32-bit DLL driver
for user programming under Windows 95/98/NT operating system. We
dvise users to program the PCI-1712/1712L using 32-bit DLL driver
provided by Advantech to avoid the complexity of low-level program-
ming by register.
The most important consideration in programming the PCI-1712/1712L
at the register level is to understand the function of the card’s regis-
ters. The information in the following sections is provided for users
who would like to do their own register-level programming.
D.2 I/O Port Address Map
The PCI-1712/1712L requires 50 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+8 is the base address plus eight bytes. The following
sections give the detailed information about register layout, and also
the detailed information about each register or driver and its address
relative to the card’s base address.
Table D-1 shows the function of each register or driver and its address
relative to the card’s base address.
Note
✎ All base address is in hexadecimal in Appendix D.
✎ Users have to use a 16-bit (word) I/O command to read/write each
register.
