代码说明：

  开关数据加载到寄存器并显示的设计与实现.3． 设计一个可以把4个开关的内容存储到一个4位寄存器的电路，并在最右边的7段显示管上显示这个寄存器中的十六进制数字。我们使用到去抖动模块clock_pulse， 用btn[0]作为输入；8位寄存器模块，用btn[1]作为加载信号；7段显示管上的显示模块x7segbc；分频模块clkdiv，用以产生模块clock_pulse和x7segbc的clk190时钟信号。(Design of switching data is loaded into the register and display the.3. design and implementation of a 4 switch content storage circuit to a 4 bit register, and in the 7 section of the most on the right shows the register in the sixteen decimal digital display tube. We used to go to the jitter module clock_pulse, with btn[0] as the input 8 bit register module, as the loading signal by btn[1] 7 segment display module on the x7segbc pipe frequency module clkdiv, clk190 clock signal for generating module clock_pulse and x7segbc.)
