- ===============================================================================
-
- *** WakeUp pin configuration ***
- ================================
- [..]
- (+) WakeUp pin is used to wakeup the system from Standby mode. This pin is
- forced in input pull down configuration and is active on rising edges.
- (+) There are two WakeUp pins, and up to eight Wakeup pins on STM32F07x & STM32F09x devices.
- (++)WakeUp Pin 1 on PA.00.
- (++)WakeUp Pin 2 on PC.13.
- (++)WakeUp Pin 3 on PE.06.(STM32F07x/STM32F09x)
- (++)WakeUp Pin 4 on PA.02.(STM32F07x/STM32F09x)
- (++)WakeUp Pin 5 on PC.05.(STM32F07x/STM32F09x)
- (++)WakeUp Pin 6 on PB.05.(STM32F07x/STM32F09x)
- (++)WakeUp Pin 7 on PB.15.(STM32F07x/STM32F09x)
- (++)WakeUp Pin 8 on PF.02.(STM32F07x/STM32F09x)
-
- *** Low Power modes configuration ***
- =====================================
- [..]
- The devices feature 3 low-power modes:
- (+) Sleep mode: Cortex-M0 core stopped, peripherals kept running.
- (+) Stop mode: all clocks are stopped, regulator running, regulator
- in low power mode
- (+) Standby mode: 1.2V domain powered off (mode not available on STM32F0x8 devices).
-
- *** Sleep mode ***
- ==================
- [..]
- (+) Entry:
- The Sleep mode is entered by using the HAL_PWR_EnterSLEEPMode(PWR_MAINREGULATOR_ON, PWR_SLEEPENTRY_WFx)
- functions with
- (++) PWR_SLEEPENTRY_WFI: enter SLEEP mode with WFI instruction
- (++) PWR_SLEEPENTRY_WFE: enter SLEEP mode with WFE instruction
-
- (+) Exit:
- (++) Any peripheral interrupt acknowledged by the nested vectored interrupt
- controller (NVIC) can wake up the device from Sleep mode.
-
- *** Stop mode ***
- =================
- [..]
- In Stop mode, all clocks in the 1.8V domain are stopped, the PLL, the HSI,
- and the HSE RC oscillators are disabled. Internal SRAM and register contents
- are preserved.
- The voltage regulator can be configured either in normal or low-power mode.
- To minimize the consumption.
-
- (+) Entry:
- The Stop mode is entered using the HAL_PWR_EnterSTOPMode(PWR_MAINREGULATOR_ON, PWR_STOPENTRY_WFI )
- function with:
- (++) Main regulator ON.
- (++) Low Power regulator ON.
- (++) PWR_STOPENTRY_WFI: enter STOP mode with WFI instruction
- (++) PWR_STOPENTRY_WFE: enter STOP mode with WFE instruction
- (+) Exit:
- (++) Any EXTI Line (Internal or External) configured in Interrupt/Event mode.
- (++) Some specific communication peripherals (CEC, USART, I2C) interrupts,
- when programmed in wakeup mode (the peripheral must be
- programmed in wakeup mode and the corresponding interrupt vector
- must be enabled in the NVIC)
-
- *** Standby mode ***
- ====================
- [..]
- The Standby mode allows to achieve the lowest power consumption. It is based
- on the Cortex-M0 deep sleep mode, with the voltage regulator disabled.
- The 1.8V domain is consequently powered off. The PLL, the HSI oscillator and
- the HSE oscillator are also switched off. SRAM and register contents are lost
- except for the RTC registers, RTC backup registers and Standby circuitry.
- The voltage regulator is OFF.
-
- (+) Entry:
- (++) The Standby mode is entered using the HAL_PWR_EnterSTANDBYMode() function.
- (+) Exit:
- (++) WKUP pin rising edge, RTC alarm (Alarm A), RTC wakeup,
- tamper event, time-stamp event, external reset in NRST pin, IWDG reset.
-
- *** Auto-wakeup (AWU) from low-power mode ***
- =============================================
- [..]
- The MCU can be woken up from low-power mode by an RTC Alarm event, an RTC
- Wakeup event, a tamper event, a time-stamp event, or a comparator event,
- without depending on an external interrupt (Auto-wakeup mode).
-
- (+) RTC auto-wakeup (AWU) from the Stop and Standby modes
-
- (++) To wake up from the Stop mode with an RTC alarm event, it is necessary to
- configure the RTC to generate the RTC alarm using the HAL_RTC_SetAlarm_IT() function.
-
- (++) To wake up from the Stop mode with an RTC Tamper or time stamp event, it
- is necessary to configure the RTC to detect the tamper or time stamp event using the
- HAL_RTC_SetTimeStamp_IT() or HAL_RTC_SetTamper_IT() functions.
-
- (++) To wake up from the Stop mode with an RTC WakeUp event, it is necessary to
- configure the RTC to generate the RTC WakeUp event using the HAL_RTC_SetWakeUpTimer_IT() function.
-
- (+) Comparator auto-wakeup (AWU) from the Stop mode
-
- (++) To wake up from the Stop mode with a comparator wakeup event, it is necessary to:
- (+++) Configure the EXTI Line associated with the comparator (example EXTI Line 22 for comparator 2)
- to be sensitive to to the selected edges (falling, rising or falling
- and rising) (Interrupt or Event modes) using the EXTI_Init() function.
- (+++) Configure the comparator to generate the event.
