/**
  * @brief Enter Stop mode
  * @note  This API is named HAL_PWR_EnterSTOPMode to ensure compatibility with legacy code running
  *        on devices where only "Stop mode" is mentioned with main or low power regulator ON.
  * @note  In Stop mode, all I/O pins keep the same state as in Run mode.          
  * @note  All clocks in the VCORE domain are stopped; the PLL, the MSI, 
  *        the HSI and the HSE oscillators are disabled. Some peripherals with the wakeup capability 
  *        (I2Cx, USARTx and LPUART) can switch on the HSI to receive a frame, and switch off the HSI 
  *        after receiving the frame if it is not a wakeup frame. In this case, the HSI clock is propagated 
  *        only to the peripheral requesting it.
  *        SRAM1, SRAM2 and register contents are preserved.
  *        The BOR is available.
  *        The voltage regulator can be configured either in normal (Stop 0) or low-power mode (Stop 1).  
  * @note  When exiting Stop 0 or Stop 1 mode by issuing an interrupt or a wakeup event,

示例11: PWR_EnterSTOPMode

/**
  * @brief  Enters STOP mode.
  * @note   In Stop mode, all I/O pins keep the same state as in Run mode.
  * @note   When exiting Stop mode by issuing an interrupt or a wakeup event, 
  *         the HSI RC oscillator is selected as system clock.
  * @note   When the voltage regulator operates in low power mode, an additional 
  *         startup delay is incurred when waking up from Stop mode. 
  *         By keeping the internal regulator ON during Stop mode, the consumption 
  *         is higher although the startup time is reduced.
  * @param  PWR_Regulator: specifies the regulator state in STOP mode.
  *         This parameter can be one of the following values:
  *             @arg PWR_Regulator_ON: STOP mode with regulator ON
  *             @arg PWR_Regulator_LowPower: STOP mode with regulator in low power mode
  * @param  PWR_STOPEntry: specifies if STOP mode in entered with WFI or WFE instruction.
  *         This parameter can be one of the following values:
  *             @arg PWR_STOPEntry_WFI: enter STOP mode with WFI instruction
  *             @arg PWR_STOPEntry_WFE: enter STOP mode with WFE instruction
