     近来用的lpc9401芯片,仿真器用的是周工的tks-936, 仿真环境用的是keil c, 不知为啥原因,就是进入不了rtc中断, 连tmr0,tmr1中断也进如不了,希望能有用过的朋友指点一,二,不胜感激,期待中,

RTCCON=0X63;            //配置rtc时钟,打开,                  
                                                                     
IEN0=0XC0;                //只将time0,time1,rtc中断打开          
IEN1=0X01;                //将其他所有中断关闭 ,但要打开iic中断  
IP0=0XFF;                                                            
IP0H=0XFF;                                                           
IP1=0XFF;                                                            
IP1H=0XFF;                                                           

上面是写的各个配置,请帮忙看看有没问题? 谢谢!
