Description: Load DAC by SPI protocol
-- Unit provides serial load of DAC trough SPI 3-wire serial interface
-- It sends 24-bit word, format of the word:
-- 4-bit command: C3-C0, 4x don t care bits, 12-bit data: d11-d0, 4x don t care bits
--
-- Serial interface outputs:
-- SDI - Serial Interface Data sent to DAC
-- SCK - Serial Interface Clock
-- CSLD - Serial Interface Chip Select/Load
--
-- DAC word length = 24 bit:
-- --------------------------
-- MSB
-- 4 bits - DAC command
-- 4 bits - don t care values
-- 12 bits - "gain" word
-- 4 bits - don t care values
-- LSB
-- --------------------------

Description: 通过SPI接口给一段位宽16位长度为8的配置寄存器进行赋值。这些配置寄存器均要求可读可写。并编写激励进行测试，先写后读，验证功能正确性。SPI接口电路的具体要求如下：
（1）输入信号为全局复位信号reset，片选信号cs，串行输入时钟信号sclk，串行数据输入信号sdi和串行数据输出信号sdo。
（2）每个传输周期进行一次16位的数据传输。每个传输周期内共传输24比特的数据，其中最开始的两个比特为10时表示读操作，最开始的两个比特为11时表示写操作，接着6个比特表示地址信息，再接下来的16个比特表示数据信息
-Through the SPI interface to a period of 16 length is 8-bit wide configuration register assignment. These configuration registers are readable and writable. And to prepare excitation test, read-after-write, verify functional correctness. Specific requirements SPI interface circuit as follows:
(1) the input signal is a global reset signal reset, chip signal cs, serial input clock signal sclk, serial data input signal and a serial data output signal sdi sdo.
(2) Each transmission cycle time 16-bit data transfer. A total of 24 bits of data transmission in each transmission cycle, wherein the top two bits 10:00 indicates a read operation, the top two bits 11:00 represented a write operation, then six bits represent address information, and then the next the 16 bits of data representing information
