单项选择题

The indirect decoding method means that the IO interface addressing requires at least two bus operations. The first bus operation outputs and latches the address through the data bus to the address port in the IO interface. The second bus operation can realize the communication of other ports of the IO interface,whose address is the address latched in the address port.
间接译码方式意味着IO接口寻址至少需要两次总线操作,第一次总线操作将地址输出并锁存在IO接口的地址端口,第二次总线操作实现IO接口该地址端口锁存地址对应的其他端口的信息传输。
