作为莫托洛拉微处理机的延伸线——MC6800型外围设备接口控制器能与MC68000直接兼容。某些对MC68000微处理机特别有用的设备有如下列:MC6821型外围设备接口适配器MC6840型可编程定时器MC6843型软磁盘控制器MC68488型通用接口适配器MC6849型双密度软磁盘控制器MC6850型异步通信接口MC6852型同步串行数据适配器MC6854型同步数据链路控制器将同步的MC6800外围设备和不同步的MC68000微处机相接口,所用的甚本原理无非是当处理机识别一个MC6800外围设备的地址时,它不得不服从MC6800时序的要求。这是可能的,因为两个处理机都能利用同一个按存储器编址的输入/输出结构。当
As an extension of the Motolora microprocessors - the MC6800 Peripheral Interface Controller is directly compatible with the MC68000. Some of the devices that are particularly useful for the MC68000 microprocessor are the following: MC6821 Peripheral Interface Adapters MC6840 Programmable Timers MC6843 Soft Disk Controller MC68488 Universal Interface Adapter MC6849 Dual Density Soft Disk Controller MC6850 Asynchronous Communication Interface MC6852 Synchronous Serial Data Adapter The MC6854 synchronous data link controller interfaces a synchronous MC6800 peripheral with an asynchronous MC68000 microcomputer. The very basic principle used is that when the processor recognizes the address of an MC6800 peripheral, Had to obey MC6800 timing requirements. This is possible because both processors can utilize the same memory-addressed input / output structure. when
