新手寄存器为啥点不亮LED2，目前只有LED1闪烁


int main()
{
  RCC_APB2ENR |= (1<<4);     //&iquest;&ordf;&AElig;&ocirc;GPIOC&para;&Euml;&iquest;&Uacute;&Ecirc;&sup1;&Auml;&Uuml;&Ecirc;±&Ouml;&Oacute;
  GPIOC_CRL &= ~(0x0f <<(4*0));
  GPIOC_CRL |= (3<<(4*0));
  
//  GPIOC_BSRR =(1<<(16+0));   //&micro;&atilde;&Aacute;&Aacute;LED1
//  GPIOC_BSRR =(1<<(16+1));   //&micro;&atilde;&Aacute;&Aacute;LED2
  
//  GPIOC_ODR =0x01;
  
  while(1)
  {
   GPIOC_BSRR =(1<<(16+0)); //&micro;&atilde;&Aacute;&Aacute;LED1
   delay(0xfffff);
   GPIOC_BSRR =(1<<(0));   //&Iuml;¨&Atilde;&eth;LED1
   delay(0xfffff);
   GPIOC_BSRR =(1<<(16+1)); //&micro;&atilde;&Aacute;&Aacute;LED2

   delay(0xffff);
  }
// return 0;
