Detailed Description

Low power library for STM32F4xx devices - http://stm32f4-discovery.com/2014/10/library-39-power-consumption-modes-for-stm32f4.

This library can put MCU into 3 different modes:

SLEEP mode

Cortex-M4 core is stopped
Peripherals kept running
How to enter this mode?
- Use TM_LOWPOWER_SleepUntilInterrupt() or
- Use TM_LOWPOWER_SleepUntilEvent();
How to exit this mode?
- Any peripheral interrupt acknowledged by the nested vectored interrupt controller (NVIC)

STOP mode

All clocks in 1.2V domain are stopped
PLL, HSI and HSE RC oscillators disabled
Internal SRAM and register contents are preserved
Voltage regulator in low-power mode
How to enter this mode?
- Use TM_LOWPOWER_StopUntilEvent() or
- Use TM_LOWPOWER_StopUntilInterrupt()
How to exit this mode?
- Any EXTI Line (Internal or External) configured in Interrupt/Event mode

STANDBY mode

Cortex-M4 deepsleep mode
Voltage regulator disabled
1.2V domain consequently powered off
PLL, HSI and HSE RC oscillators disabled
SRAM and register contents are lost except for the RTC registers, RTC backup registers, backup SRAM and Standby circuitry
How to enter this mode?
- Use TM_LOWPOWER_Standby() function
How to exit this mode?
- Wakeup pin rising edge
- RTC alarm (Alarm A and B) and wakeup
- tamper and time-stamp event
- external reset in NRST pin
- IWDG reset
