Description: GM814X SPI 接口为从机方式，各子串口的工作波特率、数据帧长等各种通信设置都可由软件设置，减少了外部MCU 的IO 需求。芯片的功耗低，具备多种掉电操作,该芯片的外部控制少，应用灵活，编程使用简单，适合于大多数多串口扩展需要的应用。
驱动源代码-GM814X SPI interface for the slave mode, the son of the work of the serial baud rate, data communications and other帧长settings can be set by software, reducing the demand for external MCU of IO. Chip, low power consumption with multiple power-down operation, the chip less external control, application flexibility, programming using a simple, suitable for most multi-serial port expansion needs of the application.

Description: 文件说明
1. 该函数包仅用于GM814x的操作，包含了对该芯片的配置寄存器读写、数据收发、软件shutdown、
软件wakeup操作，以及对接收数据的分析处理。
2. 该函数包中部分变量名和宏定义需与外部主程序一致，具体请参见源文件。
3. 该函数包中调用的三个函数ClrCS（)，SetCS()，SPITransmit(unsigned char c)需要
用户根据所用的单片机系统编写相应源代码，并注意函数名的统一。
4. 该函数包中串口号变量N由0～3分别表示串口1，串口2，串口3和串口4。
5. 该函数包的源代码可由用户根据自己的情况做修改。
6. 若用户需考虑本函数包占用的RAM资源问题，可根据需要选择需要的函数，
或自己根据GM814x的数据手册自行编写对GM814x的所有操作程序。-File Description 1 This function is only used GM814x operation package that contains the chip configuration register read and write, send and receive data, software shutdown, software wakeup operation, as well as receive data analysis and processing. (2) The name of the variable part of the package functions and macros defined in the main program to be consistent with the external details, see the source file. 3 This function package called three functions ClrCS (), SetCS (), SPITransmit (unsigned char c) requires the user depending on the preparation of the corresponding source code SCM system, and note that the function name of unity. 4 The function package serial number variable N from 0 to 3, respectively, a serial port, serial port 2, port 3 and port 4. 5 The function package' s source code by the user to make changes according to their own situation. 6 If the user needs to take into account the function of RAM resources package, may need to select the desired function, or thei
