本程序为完成各种中断的演示，使用步骤如下：
1.板子接上9V直流电压
用USB线连接J16到PC主机的USB口
连接串口(J12)到PC机的串口(COM 1)
连接串口(J8)到PC机的串口(COM 2)
2.打开SAMBA，
将文件
/compil/FLASH_FLASH/Exe/BasicInterrupt.bin
下到flash，按下复位键PB5,即可运行
3.观察运行的效果前的准备
先关掉SAMBA
关掉板子电源
打开两个超级终端，分别配置为COM1,COM2,
波特率都是115200,数据位 8，奇偶检验 无，停止位 1，数据流控制 无；
4.观察运行的效果
板子再次上电
在超级终端(COM2)显示信息:

================================================
== 欢迎使用英贝德公司的产品 ==
== EBDSAM7X 各种中断的演示测试 ==
== 更多的的帮助请到 http://www.szembed.com ==
==============================================
在键盘上输入任意键，即在超级终端(COM2)上打印输出
下面的信息在在超级终端(COM1)显示：
代表背景程序的发光二极管DS2不停闪亮，表示程序在运行中……
每隔一定时间进入software_interrupt，DS3闪一次，同时终端打印出 -I- soft interrupt
每隔几秒时间DS4闪一次，代表timer0进一次定时中断
DS5闪一次，代表timer1进一次定时中断，定地时间比timer0短，所以闪的快！呵呵！
按下PB2,进入PIO中断，DS3闪亮，同时终端打印出 -I- pio interrupt
连接串口(J9)到PC机的串口(COM 2),上电时也打印出一段信息

5.代码说明：
1)完成基本的初始化
2)初始化PIO,IRQ,FIQ,software_interrupt等
3)驱动板上的四个按键(PB1,PB2,PB3,PB4)
4)初始化DEBUG口，Usart0,Usart1等
5)初始化定时器timer0,timer1等
