关于hz128锁相环设置问题

fastaction

各位大侠：
我在使用mc9shz128 的锁相环 功能，将外部8mhz晶振倍频到50mhz,对相关寄存器做如下设置：
 
void CPU_init(void)
{
    asm("nop");                   //nop instruction
 
    INITRM=0x39;                  //Internal RAM Position Register  ram location 0x2800-0x3fff
                                  //RAM15=0,RAM14=0,RAM13=1,RAM12=1,RAM11=1,??=0,??=0,RAMHAL=1
    INITEE=0x01;                  //Internal EEPROM Position Register EEON=1 ;ENABLE E2PROM
                                  //EE15=0,EE14=0,EE13=0,EE12=0,??=0,??=0,??=0,EEON=1
                                 
    MISC=0x0D;                    //Miscellaneous System Control Register
                                  //??=0,??=0,??=0,??=0,EXSTR1=1,EXSTR0=1,ROMHM=0,ROMON=1
    CRGINT=0X00;                              
                                 
    EBICTL=0x00;                  //External Bus Interface Control Register
                                  //??=0,??=0,??=0,??=0,??=0,??=0,??=0,ESTR=0
                                 
    PEAR=0x10;                    //Port E Assignment Register  NORMAL siggle chip mode
   
   
                                  //NOACCE=0,??=0,PIPOE=0,NECLK=1,LSTRE=0,RDWE=0,??=0,??=0
    CLKSEL=0x00;                  //CRG Clock Select Register
   
   
                                  //PLLSEL=0,PSTP=0,SYSWAI=0,ROAWAI=0,PLLWAI=0,CWAI=0,RTIWAI=0,COPWAI=0
   // PLLCTL=0x00;                //CRG PLL Control Register
                                  //PLLON=0
    PLLCTL_CME=0; 
    PLLCTL_SCME=0;                          
                                 
    SYNR=0x18;                    //CRG Synthesizer Register
                                  //??=0,??=0,SYN5=0,SYN4=1,SYN3=1,SYN2=0,SYN1=0,SYN0=0
    REFDV=0x07;                   //CRG Reference Divider Register
                                  //??=0,??=0,??=0,??=0,REFDV3=0,REFDV2=1,REFDV1=1,REFDV0=1
    PLLCTL_PLLON=1 ;
    PLLCTL_AUTO=1 ;                         
    asm("nop")
    asm("nop")
                                                
    while(CRGFLG_LOCK==0){asm("nop");} //时钟是否稳定  
  
    CLKSEL=0x80;                  //CRG Clock Select Register
                                  //PLLSEL=1
                                 
    INTCR_IRQEN=0;                              
                                                             
}
仿真 结果 CRGFLG_LOCK一直都没置1,是不是哪个寄存器设置有问题，烦请指点，不胜感激。

你仿真的时候，看一下命令窗口提示的是什么，你可以给我看一下吗？

如果不能走下去说明你的配置有问题。把下面2句放在CLKSEL=0x00; 前面试试。
SYNR=0x18;
REFDV=0x07;
