Appendix C Register Structure and
Format
C.1 Overview
The PCI-1761 is delivered with an easy-to-use 32-bit DLL driver for user
programming under the Windows 95/98/NT/2000 operating system. We
advise users to program the PCI-1761sing the 32-bit DLL driver provided
by Advantech to avoid the complexity of low-level programming by reg-
ister.
The most important consideration in programming the PCI-1761 the reg-
ister level is to understand the function of the card's registers. The infor-
mation 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-1761 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.
Table C-1 shows the function of each register of the PCI-1761 or driver
and its address relative to the card's base address.
