摘要
给出了一种在１６位单片微机系统中实现１６位／８位数据总线通用的硬件设计方法。该方法既保留了１６位数据总线快速存取数据的特点，又较好地解决了１６位机系统与８位智能外设实现数据总线共享的问题，从而使ＭＣＳ－９６１６位单片微机系统的外设选择具有更大的灵活性。
A method of designing the hardware of 16-bit/8-bit common data bus is presented. Bythis method the instant input and output of data in the 16-bit data bus is maintained and the pyoblcm issolved of how use the data bus between 16-bit microcontroller system and 8-bit illtellectual extra device of MCS-96 16-bit single chip microcontroller system.
