其中start是开始信号，上升沿启动控制单元；CLK是工作时钟；CtrlAddr是读取控制字时的地址；CtrlData是读取的控制字；Reading是读信号；EOP是本次AD采样完成信号，只有当AD1和AD2均完成后EOP才为高；EN是允许信号，启动分频器、地址发生器；N是分频系数；Addr1和Addr2分别是AD1和AD2数据存储的起始地址；NUM1和NUM2分别是采样点数。

控制字分别表示分频系数为2，AD1起始地址为1，采样点数5，AD2起始地址为3，采样点数为4。

-Where start is the start signal, the rising edge of start control unit　CLK is a working clock　CtrlAddr is to read the control word address　CtrlData is to read the control word　Reading is a reading of the signal　EOP is a sampling completion signal of this AD, only When the AD1 and AD2 are completed only after the EOP is high　EN is the enable signal to start the divider, the address generator　N is the frequency factor　Addr1 and Addr2 AD1 and AD2 are the starting address of data storage　NUM1 and NUM2 sampling points, respectively. Control word frequency factor, respectively, 2, AD1 starting address is 1, sampling point 5, AD2 start address is 3, the sampling points to 4.
