Functions
void	EMU_DCDCConductionModeSet (EMU_DcdcConductionMode_TypeDef conductionMode, bool rcoDefaultSet)
	Set DCDC LN regulator conduction mode. More...

bool	EMU_DCDCInit (const EMU_DCDCInit_TypeDef *dcdcInit)
	Configure DCDC regulator. More...

void	EMU_DCDCLnRcoBandSet (EMU_DcdcLnRcoBand_TypeDef band)
	Set DCDC Low-noise RCO band. More...

void	EMU_DCDCModeSet (EMU_DcdcMode_TypeDef dcdcMode)
	Set DCDC regulator operating mode. More...

void	EMU_DCDCOptimizeSlice (uint32_t em0LoadCurrent_mA)
	Optimize DCDC slice count based on the estimated average load current in EM0. More...

bool	EMU_DCDCOutputVoltageSet (uint32_t mV, bool setLpVoltage, bool setLnVoltage)
	Set DCDC output voltage. More...

bool	EMU_DCDCPowerOff (void)
	Power off the DCDC regulator. More...

void	EMU_EM23Init (const EMU_EM23Init_TypeDef *em23Init)
	Update EMU module with Energy Mode 2 and 3 configuration. More...

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...

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.

void	EMU_UpdateOscConfig (void)
	Update EMU module with CMU oscillator selection/enable status. More...
