Introduction
PCL-722是一个完全的PC附加卡,可以提供144可编程数字I/O线,并被分为6个主要端口.这些端口在mode 0中效仿了一个8255得可编程序外围接口的实施,但是提供了比8255更高的操纵能力.每一个端口依次组成3个辅助8位端口(A,B,C).您可以独自用软件为输入和输出来配置这些8位端口.

The PCL-722 is a full-size PC add-on card that offers 144 programmable digital I/O lines divided into six main ports. Each port emulates the operation of an 8255 Programmable Peripheral Interface (PPI) in mode 0 but provides higher driving capacity than the 8255. Each port in turn consists of three subsidiary 8-bit ports (A, B, C). You can individually configure each of these 8-bit ports by software for input or output.
