刚学S3C44B0X不久，由于很菜，调了很久没都进中断，最好发现问题出在没加中断重映射#include"44b.h"#include"option.h"int i;void __irq EINT4567 (void);void IO_Init(){rPCONC = 0X55555555;rPDATC = 0X4;rPCONG = 0XFF00;//rPUPG = 0X0;}void INT_Init(){rEXTINT = 0X0;rEXTINTPND = 0Xff;rINTCON = 0X5;rINTMOD = 0X0;rINTMSK = ~(BIT_GLOBAL|BIT_EINT4567);//rI_ISPC = 0X3FFFfff;}int Main(){for(i=_RAM_STARTADDRESS;i <(_RAM_STARTADDRESS+0x20);i+=4) { *((volatile unsigned *)i)=0xEA000000+0x1FFE; } pISR_EINT4567 = (int)EINT4567;IO_Init();INT_Init();while(1);}void __irq EINT4567 (void){if( (rEXTINTPND & (1<<0) ) != 0){rPDATC = 0X2;rEXTINTPND |= (1 << 0);}if( (rEXTINTPND & (1<<1) ) != 0){rPDATC = 0X4;rEXTINTPND |= (1 << 1);}if( (rEXTINTPND & (1<<2) ) != 0){rPDATC = 0X8;rEXTINTPND |= (1 << 2);}if( (rEXTINTPND & (1<<3) ) != 0){rPDATC = 0X0;rEXTINTPND |= (1 << 3);}rI_ISPC |= BIT_EINT4567;rEXTINTPND = 0Xff;}

就是这句：

for(i=_RAM_STARTADDRESS;i <(_RAM_STARTADDRESS+0x20);i+=4)
{
*((volatile unsigned *)i)=0xEA000000+0x1FFE;
}

现在终于进中断了
