The purpose of this example is to demonstrate that the functioning of External interrupts (INT0, INT1, INT4, INT5 and INT6) and how toset them up. This directory contains the frameworks fw.c, the test program extr_intr.c and the external interrupt service routines isr.c. This was compiled using micro vision2.

ARMask.The ARM has six operating modes: • User (unprivileged mode under which most tasks run) • FIQ (entered when a high priority (fast) interrupt is raised) • IRQ (entered when a low priority (normal) interrupt is raised) • Supervisor (entered on reset and when a Software interrupt instruction is executed) • Abort (used to handle memory access violations) • Undef (used to handle undefined instructions) * ARM Architecture Version 4 adds a seventh mode: • System (privileged mode using the same registers as user mode)

这是PC机间相互通信的例子，程序“require”为用查询方式实现，程序“interrupt”为 用中断方式实现

(1) 用单脉冲发生器的输出作为中断请求信号使8259A产生中断,进入中断后显示一个字符串。(2) 中断请求通过8259的IRQ2端输入，中断源可以是片外8253定时器输出的脉冲，并把8253的OUTO和总线槽IR02连接好。 (3) 编写程序,要求每次主机响应外部中断IRQ2时,显示字符串“THIS IS A 8259A interrupt!”(或其它串)，中断十次后，程序退出。
