LL_LPM_EnableSleep()

__STATIC_INLINE void LL_LPM_EnableSleep

(

void

)

Processor uses sleep as its low power mode @rmtoll SCB_SCR SLEEPDEEP LL_LPM_EnableSleep.

Return values

None

{
  /* Clear SLEEPDEEP bit of Cortex System Control Register */
  CLEAR_BIT(SCB->SCR, ((uint32_t)SCB_SCR_SLEEPDEEP_Msk));
}

LL_LPM_EnableDeepSleep()

__STATIC_INLINE void LL_LPM_EnableDeepSleep

(

void

)

Processor uses deep sleep as its low power mode @rmtoll SCB_SCR SLEEPDEEP LL_LPM_EnableDeepSleep.

Return values

None

{
  /* Set SLEEPDEEP bit of Cortex System Control Register */
  SET_BIT(SCB->SCR, ((uint32_t)SCB_SCR_SLEEPDEEP_Msk));
}

LL_LPM_EnableSleepOnExit()

__STATIC_INLINE void LL_LPM_EnableSleepOnExit

(

void

)

Configures sleep-on-exit when returning from Handler mode to Thread mode.

Note

Setting this bit to 1 enables an interrupt-driven application to avoid returning to an empty main application. @rmtoll SCB_SCR SLEEPONEXIT LL_LPM_EnableSleepOnExit

Return values

None

{
  /* Set SLEEPONEXIT bit of Cortex System Control Register */
  SET_BIT(SCB->SCR, ((uint32_t)SCB_SCR_SLEEPONEXIT_Msk));
}

LL_LPM_DisableSleepOnExit()

__STATIC_INLINE void LL_LPM_DisableSleepOnExit

(

void

)

Do not sleep when returning to Thread mode. @rmtoll SCB_SCR SLEEPONEXIT LL_LPM_DisableSleepOnExit.

Return values

None

{
  /* Clear SLEEPONEXIT bit of Cortex System Control Register */
  CLEAR_BIT(SCB->SCR, ((uint32_t)SCB_SCR_SLEEPONEXIT_Msk));
}

LL_LPM_EnableEventOnPend()

__STATIC_INLINE void LL_LPM_EnableEventOnPend

(

void

)

Enabled events and all interrupts, including disabled interrupts, can wakeup the processor. @rmtoll SCB_SCR SEVEONPEND LL_LPM_EnableEventOnPend.

Return values

None

{
  /* Set SEVEONPEND bit of Cortex System Control Register */
  SET_BIT(SCB->SCR, ((uint32_t)SCB_SCR_SEVONPEND_Msk));
}

LL_LPM_DisableEventOnPend()

__STATIC_INLINE void LL_LPM_DisableEventOnPend

(

void

)

Only enabled interrupts or events can wakeup the processor, disabled interrupts are excluded @rmtoll SCB_SCR SEVEONPEND LL_LPM_DisableEventOnPend.

Return values

None

{
  /* Clear SEVEONPEND bit of Cortex System Control Register */
  CLEAR_BIT(SCB->SCR, ((uint32_t)SCB_SCR_SEVONPEND_Msk));
}
