四、外围接口与M6800微处理机的联接外围接口电路与微处理机的联接问题是微处理机应用技术的一个关键问题,也是应用者十分关注的问题。首先,应该特别指出的是,微处理机系列的设计者为了使机器具有灵活机动、适用性广的特点,也都在主机的外围接口上下了很大的功夫,例如M6800系列专门提供 Fourth, the peripheral interface and M6800 microprocessor connection Peripheral interface circuit and microprocessor connection problem is a key issue of microprocessor application technology, but also the user is very concerned about the problem. First of all, it should be particularly pointed out that the microprocessor family designers in order to make the machine flexible and adaptable features, but also in the host peripheral interface a lot of work, such as the M6800 series specifically provide
