1、用状态机设计A/D转换器ADC0809的采样控制电路，并在数码管上显示转换结果； 2、设置有复位和启动/保持开关，要求 ⑴ 复位开关用来使A/D转换器复位，并做好A/D转换准备； ⑵ 启动/保持开关用来控制A/D转换器开始连续转换或停止转换保持结果，即按一下启动/保持开关，启动A/D转换器开始转换，再按一下启/停开关，停止转换并保持结果。 3、采用Verilog HDL语言设计符合上述功能要求的控制电路。(1, with the state machine design A/D converter ADC0809 sampling control circuit and display the results on the digital conversion 2 is provided with a reset and start/hold switch, reset switch is used to make the request ⑴ A/D converter reset and do A/D conversion ready ⑵ start/hold switch is used to control the A/D converter starts converting or stop the conversion to maintain a continuous result that by clicking Start/hold switch, start the A/D converter to start the conversion, and then Click the start/stop switch stops the conversion and keep the results. 3, using Verilog HDL language designed to meet the functional requirements of the above-mentioned control circuit.)

SHIFT_8REG是8位的一个具有移位功能的寄存器，每一次数据打入都会从这个寄存器的最低位打入，并相应进行向左移位。 ODD_110BREG是一个3位的备份寄存器，寄存器中存放的是奇数帧的同步头，也就是110。 EVEN_9BHREG是一个8位的备份寄存器，寄存器中存放的是偶数帧的同步头，也就是10011011。这两个寄存器的初始值在系统一开始就打入。 -SHIFT_8REG is eight with a displacement of the functional Register, Each will enter the data from the register into the lowest point, and the left shift accordingly. ODD_110BREG is a three backup Register, the Register is stored in the odd frame synchronization head, is 110. EVEN_9BHREG 8 is a backup Register, which register is kept even the first frame synchronization, is 10011011. This register the two initial value of the system into a start.
