时钟脉冲

By continuing to send pulses at CLK, the contents of the following byte addresses can be read out of the device.

通过继续发送时钟脉冲，以下字节地址的内容可以读出装置。

R is raised while Clk is low, to disable address counter incrementfor one clock pulse.

1－当Reset为高，而Clk为低，禁止地址计数器在每个时钟脉冲时自加。

After this period, the first clock pulse is generated.

经过这一时期，第一个时钟脉冲产生。

When the count value is 0, the next clock pulse presets the data to invert the output.

当计数值是0，下一个时钟脉冲预置的数据转化输出。

One is used to give out clock pulse to control the velocity, another is used to give out directional signal to control the direction.

一条发出时钟脉冲信号来控制步进电机的转速；另一条发出转向信号控制步进电机的转向。

One is used to give out clock pulse to control thevelocity, another is used to give out directional signal to controlthe direction.

一条发出时钟脉冲信号来控制步进电机的转速；另一条发出转向信号控制步进电机的转向。

According to the demand of controlling speed, the system give out corresponding clock pulse to control the speed of the motor through the clock pulse.

控制系统按速度控制的要求从时钟脉冲控制线发出相应的控制脉冲即可对步进电机的转速进行控制。

It is called a shift register because the data is shifted through the register by one bit position on each clock pulse.

这就是移位寄存器，因为数据在每一个时钟脉冲的作用下通过寄存器会移动一位。
