2：单片机对外呈三总线结构：1：由P0、P2组成16位地址总线 A0~A15（P0口分时复用为低8位地址，P2口用为高8位地址），因为是16位地址线，使片外存储器的寻址范围达到64K；
2：由P0分时复用为数据总线 D0~D7；3：由ALE、PSEN、RST、EA与P3口的INT0、INT1、T0、T1、WR、RD共10个引脚组成控制总线。

3：ALE地址锁存脉冲信号每机器周期出现两次，在不访问片外数据存储器时，由于ALE信号不出现，可用作对外输出的时钟脉冲，脉冲频率为晶振频率fosc的1/6（或机器周期的1/3），但在访问片外数据存储器时，由于ALE脉冲信号每机器周期出现两次，因而ALE脉冲会跳空一个，因此就不能作为时钟输出。

ALE一般用来连接外接地址锁存器芯片的锁存引脚。

4：51系列单片机常见的晶振频率有12MH、24MH、40MH等，振荡器输出的脉冲经2分频（分成P1、P2两相位）成为内部时钟信号，用作单片机的内部控制信号，其周期称为时钟周期，6个时钟周期构成1个机器周期。

5：设计产品时，要在关键的地方：电源、串口、看门狗的输出和输入、I/O口等加不同颜色的LED指示，便于调试；查看门狗的复位输出可在电路板上加一个下拉LED，这样比较直观。
