MCS—51单片机系统扩展
简单的并行接口由数据寄存器和少量的控制电路组成,暂存传送的数据。以锁存器、缓冲器为主要芯片,稍加控制都可以作为简单的并行接口.-MCS-51 single-chip microcomputer system to expand a simple parallel interface from the data register and a small number of control circuit components, temporary storage of data transmission. To latches, buffers as the main chip, a little control can be used as a simple parallel interface.
