An interesting feature of the Z-80 is that during I/O operations a single wait state is automatically inserted, allowing the AD574A to be used with Z-80 processors having clock speeds up to 4 MHz. For applications faster than 4 MHz use the wait state generator in Figure 16. In a memory mapped configuration the AD574A may be interfaced to Z-80 processors with clock speeds of up to 2.5 MHz.
------------------不要软件翻译的

Z-80的一个有趣的特性就是当进行I/O操作时会自动插入一个等待状态,允许AD574A和时钟频率高达4MHz的Z-80处理器一起使用。对于高于4MHz的实际应用,可以使用图16所展示的等待状态发生器。在配置内存内部,AD574A可以和时钟频率高达2.5MHz的Z-80处理器通过接口相连接。
