2812有三个独立的外部可屏蔽中断XINT1,XINT2,XINT13和一个不可屏蔽中断XNMI，外部扩展可屏蔽中断通过CPLD之后，通过按键产生一外部中断EXINT5。-2812 has three independent external maskable interrupt XINT1, XINT2, XINT13 and a non-maskable interrupt XNMI, external expansion through the CPLD can be screened a

编写TMS320LF2407的对SCI模块、SPI模块、EV中通用定时器（T1、T2、T3、T4）及捕捉逻辑（CAP1\CAP2\CAP3)、外部中断引脚（XINT1、XINT2）和CAN模块初始化程序。-Prepared for SCI module, SPI module, EV in general-purpose timer (T1, T2, T3, T4) and capture logic (CAP1 \ CAP2 \ CAP3), TMS320LF2407 external int

本程序用来测试DSP外部中断，把GPIO0、GPIO1分别设为外部中断1（Xint1）和外部中断2（Xint2），两个其他GPIO 分别作为中断的触发信号，完成中断触发。程序运行时，可以观察相应变量的变化。-This procedure is used to test the DSP external interrupt, the GPIO0, GPIO1 were set to external interrupt 1 (Xint1) and external interrupt 2 (Xin
