Introduction
PCI-1753是一款PCI总线的96路数字量I/O卡,它也可以经由PCI-1753E扩展为192路的数字量I/O口.PCI-1753仿真8255PPI模式0,但是缓存电路提供了比8255更高的驱动能力.96路I/O线分成了12个8位I/O端口:A0,B0,CO,A1,B1,C1,A2,B2,C2,A3,B3和C3.用户可以使用软件配置每个端口作为输入或输出端口.

The PCI-1753 is a 96-bit digital I/O card for the PCI bus, which can be extended to 192 digital I/O channels by connecting with its extension board, PCI-1753E. The card emulates mode 0 of the 8255 PPI chip, but the buffered circuits offer a higher driving capability than the 8255. The 96 I/O lines are divided into twelve 8-bit I/O ports: A0, B0, C0, A1, B1, C1, A2, B2, C2, A3, B3 and C3. Users can configure each port as input or output via software.
