| Abstract: | By using the tested start up code of the S3C2410, the mechanism in which ARM processor responded to sorts of exception-al interruption was thoroughly explained. Then the function of "-irq " was introduced, and the program of interruption was also de-signed. At last the initialize program of external interrupt was developed in C language by seting several important interrupt controller special registers, and the flowsheet of main program was given. |
