Description: The Serial Peripheral Interface Bus or SPI bus is a synchronous serial data link standard named by Motorola that operates in full duplex mode. Devices communicate in master/slave mode where the master device initiates the data frame. Multiple slave devices are allowed with individual slave select (chip select) lines. Sometimes SPI is called a "four wire" serial bus, contrasting with three, two, and one wire serial buses.-The Serial Peripheral Interface Bus or SPI bus is a synchronous serial data link standard named by Motorola that operates in full duplex mode.

Description: Verilog编写的SPI程序，含英文原文档说明，很全的-The OpenCores simple Serial Peripheral Interface core is an enhanced version of the
Serial Peripheral Interface found on Motorola s M68HC11 family of CPUs. The Serial
Peripheral Interface is a serial, synchronous communication protocol that requires a
minimum of 3 wires. Enhancements to the original interface include a wider
supported operating frequency range, 4 entries deep read and write FIFOs, and
programmable transfer count dependent interrupt generation. The high compatibility
with the M68HC11 SPI port ensures that existing software can use this core without
major modifications. New software can use existing examples as a starting point.
The core features an 8 bit wishbone interface.

Description: SPI（Serial Peripheral Interface）串行外围模块接口是Motorola首先在其MC68HCXX系列处理器上定义的，它是一种同步的高速串行通信协议。它可以使单片机与外围模块之间进行数据交换，比EEPROM,Flash,实时时钟，AD转换，数字信号处理器和数字信号解码器之间交换数据，同时应用比较多的是用来作为按键等外设的扩展。SPI总线系统是一种同步串行外设接口；是一种高速的，全双工，同步的通信总线，并且在芯片的管脚上只占用四根线，节约了芯片的管脚，同时为PCB的布局上节省空间，提供方便，正是出于这种简单易用的特性，现在越来越多的芯片集成了这种通信协议。SPI有主从两种工作方式，可以工作在3线或者4线模式下。-SPI (Serial Peripheral Interface) is a Serial Peripheral Interface module is Motorola first defined on the MC68HCXX series processor, it is a kind of synchronous Serial communication protocol at a high speed. It can make for data exchange between single-chip microcomputer and peripheral modules, block than the EEPROM, Flash, real-time clock, AD conversion, digital signal processor and digital signal for exchanging data between decoders, and application more is used as an extension of the peripherals like buttons. SPI bus system is a kind of synchronous serial peripheral interface Is a kind of high speed, full duplex, synchronous communication bus, and on the pin of the chip takes only four lines, saved the chip pins, save a space for PCB layout at the same time, provide a convenient, it is out of the characteristics of this kind of simple and easy to use, now more and more chip integrates the communication protocol.

SPI相关缩写
SS: Slave Select，选中从设备，片选。
CKPOL (Clock Polarity) = CPOL = POL = Polarity = （时钟）极性
CKPHA (Clock Phase) = CPHA = PHA = Phase = （时钟）相位
SCK = SCLK = SCL = SPI的时钟（Serial Clock）
Edge = 边沿，即时钟电平变化的时刻，即上升沿(rising edge)或者下降沿(falling edge)。
对于一个时钟周期内，有两个edge，分别称为：
Leading edge = 前一个边沿 = 第一个边沿，对于开始电压是1，那么就是1变成0的时候，对于开始电压是0，那么就是0变成1的时候；
Trailing edge = 后一个边沿 = 第二个边沿，对于开始电压是1，那么就是0变成1的时候（即在第一次1变成0之后，才可能有后面的0变成1），对于开始电压是0，那么就是1变成0的时候；(SPI (Serial Peripheral Interface, serial peripheral interface) is a synchronous serial data transmission standard put forward by Motorola company, is a high-speed, full duplex, synchronous communication bus, is widely used in many devices.
SPI related abbreviations
SS: Slave Select, selected from the device, chip select.
CKPOL (Clock, Polarity) = CPOL = POL = Polarity = (clock) polarity
CKPHA (Clock, Phase) = CPHA = PHA = Phase = (clock) phase
SCK = SCLK = SCL = SPI clock (Serial, Clock)
Edge = edge, instant clock, level change time, i.e. rising edge (rising, edge) or falling edge (falling, edge).
For a clock cycle, there are two edge, respectively:
Leading edge = front edge = first edge, for start voltage is 1, then 1 is 0, for start voltage is 0, then 0 is 1;
Trailing = edge = second after an edge edge, the start voltage is 1, it is 0 to 1 of the time (that is, after the first 1 to 0, it may be behind the 0 to 1), the start voltage is 0, it is 1 to 0 times;)
