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_EM4Init (const EMU_EM4Init_TypeDef *em4Init)
	Update EMU module with Energy Mode 4 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_EnterEM4H (void)
	Enter energy mode 4 hibernate (EM4H). More...
void	EMU_EnterEM4S (void)
	Enter energy mode 4 shutoff (EM4S). 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_SetBiasMode (EMU_BiasMode_TypeDef mode)
	Adjust the bias refresh rate. More...
void	EMU_UpdateOscConfig (void)
	Update EMU module with CMU oscillator selection/enable status. More...
bool	EMU_VmonChannelStatusGet (EMU_VmonChannel_TypeDef channel)
	Get the status of a voltage monitor channel. More...
void	EMU_VmonEnable (EMU_VmonChannel_TypeDef channel, bool enable)
	Enable or disable a VMON channel. More...
void	EMU_VmonHystInit (const EMU_VmonHystInit_TypeDef *vmonInit)
	Initialize VMON channel with hysteresis (separate rise and fall triggers). More...
void	EMU_VmonInit (const EMU_VmonInit_TypeDef *vmonInit)
	Initialize VMON channel. More...
