430f149 flash 写入高字节时引发PUC信号 [复制链接]

  大概写入不超过60个字节的数据
  uint i;
    uchar *Flash_IP = (uchar *)0x1000;
    FCTL3 = FWKEY;
   while(BUSY == 0);
    FCTL1 = FWKEY + ERASE;
    *Flash_IP = 0;
    FCTL1 = FWKEY + WRT;
    for(i = 0;i < 128;i ++)
    {
      *Flash_IP++ = R1data[i];
    }
    FCTL1 = FWKEY;
    FCTL3 = FWKEY + LOCK;        //  锁定
