void | EMU_EM23Init (const EMU_EM23Init_TypeDef *em23Init) |
Update EMU module with Energy Mode 2 and 3 configuration. More... | |
__STATIC_INLINE void | EMU_EM2Block (void) |
Block entering EM2 or higher number energy modes. | |
__STATIC_INLINE void | EMU_EM2UnBlock (void) |
Unblock entering EM2 or higher number energy modes. | |
void | EMU_EM4Init (const EMU_EM4Init_TypeDef *em4Init) |
Update EMU module with Energy Mode 4 configuration. More... | |
__STATIC_INLINE void | EMU_EM4Lock (bool enable) |
Enable or disable EM4 lock configuration. More... | |
__STATIC_INLINE void | EMU_EnterEM1 (void) |
Enter energy mode 1 (EM1). | |
void | EMU_EnterEM2 (bool restore) |
Enter energy mode 2 (EM2). More... | |
void | EMU_EnterEM3 (bool restore) |
Enter energy mode 3 (EM3). More... | |
void | EMU_EnterEM4 (void) |
Enter energy mode 4 (EM4). More... | |
__STATIC_INLINE void | EMU_IntClear (uint32_t flags) |
Clear one or more pending EMU interrupts. More... | |
__STATIC_INLINE void | EMU_IntDisable (uint32_t flags) |
Disable one or more EMU interrupts. More... | |
__STATIC_INLINE void | EMU_IntEnable (uint32_t flags) |
Enable one or more EMU interrupts. More... | |
__STATIC_INLINE uint32_t | EMU_IntGet (void) |
Get pending EMU interrupt flags. More... | |
__STATIC_INLINE uint32_t | EMU_IntGetEnabled (void) |
Get enabled and pending EMU interrupt flags. Useful for handling more interrupt sources in the same interrupt handler. More... | |
__STATIC_INLINE void | EMU_IntSet (uint32_t flags) |
Set one or more pending EMU interrupts. More... | |
__STATIC_INLINE void | EMU_Lock (void) |
Lock the EMU in order to protect its registers against unintended modification. More... | |
void | EMU_MemPwrDown (uint32_t blocks) |
Power down memory block. More... | |
void | EMU_RamPowerDown (uint32_t start, uint32_t end) |
Power down RAM memory blocks. More... | |
void | EMU_Restore (void) |
Restore CMU HF clock select state, oscillator enable and voltage scaling (if available) after EMU_EnterEM2() or EMU_EnterEM3() are called with the restore parameter set to false. Calling this function is equivalent to calling EMU_EnterEM2() or EMU_EnterEM3() with the restore parameter set to true, but it allows the application to evaluate the wakeup reason before restoring state. | |
__STATIC_INLINE void | EMU_Unlock (void) |
Unlock the EMU so that writing to locked registers again is possible. | |
void | EMU_UpdateOscConfig (void) |
Update EMU module with CMU oscillator selection/enable status. More... | |
