Functions

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.
 
__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_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...
