请高手指教一下,下面这个程序是个简单的定时器溢出中断的程序,但就是不对,请指教
#include <hidef.h> /* common defines and macros */
#include "derivative.h" /* derivative-specific definitions */
void ECT_Init(void)
{
TSCR2_PR = 2; //预分频系数为8
TSCR2_TOI = 1; //定时器溢出中断使能
TSCR1_TEN = 1; //定时器使能
}
void main(void) {
/* put your own code here */
ECT_Init();
DDRS =0XFF;
for(;;);
}
#pragma CODE_SEG __NEAR_SEG NON_BANKED
void interrupt TimerOverFlow(void)
{
PTS =5;
TFLG2_TOF = 1;
}
