想问一下
我用的是S3C44B0的板子,可是总进不了中断,不知道是什么原因,请大家指教一下.
程序如下:
#include"inc/44b.h"
#include"inc/option.h"
#define uchar unsigned char
#define uint unsigned int
volatile uchar flag;
void __irq Time_Do();
void Init()
{
flag=0;
pISR_TIMER1=(unsigned int)Time_Do;
rINTMSK=~(BIT_GLOBAL|BIT_TIMER1);
rINTCON=0X05;
rTCFG0=0X00F;
rTCFG1=0X04;
rTCNTB1=0XFFFF;
rTCON=0X02;
rTCON=0X01;
while(flag==0);
rTCON=0X0;
rINTMSK=BIT_GLOBAL;
}
void __irq Time_Do(void)
{
rINTMSK=BIT_TIMER1;
flag++;
}
Main()
{
Init();
while(1);
} |
