请教STM32 的上电过程?

各位高人,想请教一下,STM32的上电过程,芯片上电后,是怎么运行的,跳到哪里,从哪里取第一条指令执行,有没有相关文档可供参考.感谢!
 
另在STM32 的库文件中有个 Stm32f10x_vector.c 的文件其中中断表如下:
 
const intvec_elem __vector_table[] =
{
  { .__ptr = __sfe( "CSTACK" ) },
  __program_start,
  NMIException,
  HardFaultException,
  MemManageException,
  BusFaultException,
  UsageFaultException,
  0, 0, 0, 0,            /* Reserved */
  SVCHandler,
  DebugMonitor,
  0,                      /* Reserved */
  PendSVC,
  SysTickHandler,
  WWDG_IRQHandler,
  PVD_IRQHandler,
  TAMPER_IRQHandler,
  RTC_IRQHandler,
  FLASH_IRQHandler,
  RCC_IRQHandler,
  EXTI0_IRQHandler,
  EXTI1_IRQHandler,
  EXTI2_IRQHandler,
  EXTI3_IRQHandler,
  EXTI4_IRQHandler,
  DMAChannel1_IRQHandler,
  DMAChannel2_IRQHandler,
  DMAChannel3_IRQHandler,
  DMAChannel4_IRQHandler,
  DMAChannel5_IRQHandler,
  DMAChannel6_IRQHandler,
  DMAChannel7_IRQHandler,
  ADC_IRQHandler,
  USB_HP_CAN_TX_IRQHandler,
  USB_LP_CAN_RX0_IRQHandler,
  CAN_RX1_IRQHandler,
  CAN_SCE_IRQHandler,
  EXTI9_5_IRQHandler,
  TIM1_BRK_IRQHandler,
  TIM1_UP_IRQHandler,
  TIM1_TRG_COM_IRQHandler,
  TIM1_CC_IRQHandler,
  TIM2_IRQHandler,
  TIM3_IRQHandler,
  TIM4_IRQHandler,
  I2C1_EV_IRQHandler,
  I2C1_ER_IRQHandler,
  I2C2_EV_IRQHandler,
  I2C2_ER_IRQHandler,
  SPI1_IRQHandler,
  SPI2_IRQHandler,
  USART1_IRQHandler,
  USART2_IRQHandler,
  USART3_IRQHandler,
  EXTI15_10_IRQHandler,
  RTCAlarm_IRQHandler,
  USBWakeUp_IRQHandler,
};
 
问题:
{ .__ptr = __sfe( "CSTACK" ) } 和  __program_start, 各有什么作用,在哪里用到?
 
再次感谢各位!
 
我刚学用STM32, 很想与同道交流, QQ:28267120
