Field Documentation

◆ powerConfig

EMU_PowerConfig_TypeDef EMU_DCDCInit_TypeDef::powerConfig

Device external power configuration.

emuPowerConfig_DcdcToDvdd is currently the only supported mode.

◆ dcdcMode

EMU_DcdcMode_TypeDef EMU_DCDCInit_TypeDef::dcdcMode

DCDC regulator operating mode in EM0/1.

◆ mVout

uint16_t EMU_DCDCInit_TypeDef::mVout

Target output voltage (mV).

◆ em01LoadCurrent_mA

uint16_t EMU_DCDCInit_TypeDef::em01LoadCurrent_mA

Estimated average load current in EM0/1.

(mA). This estimate is also used for EM1 optimization; if EM1 current is expected to be higher than EM0, then this parameter should hold the higher EM1 current.

◆ em234LoadCurrent_uA

uint16_t EMU_DCDCInit_TypeDef::em234LoadCurrent_uA

Estimated average load current in EM2 (uA).

This estimate is also used for EM3 and 4 optimization; if EM3 or 4 current is expected to be higher than EM2, then this parameter should hold the higher EM3 or 4 current.

◆ maxCurrent_mA

uint16_t EMU_DCDCInit_TypeDef::maxCurrent_mA

Maximum average DCDC output current (mA).

This can be set to the maximum for the power source, for example the maximum for a battery.

◆ anaPeripheralPower

EMU_DcdcAnaPeripheralPower_TypeDef EMU_DCDCInit_TypeDef::anaPeripheralPower

Select analog peripheral power in DCDC-to-DVDD mode.

◆ reverseCurrentControl

EMU_DcdcLnReverseCurrentControl_TypeDef EMU_DCDCInit_TypeDef::reverseCurrentControl

Low-noise reverse current control.

NOTE: this parameter uses special encoding: >= 0 is forced CCM mode where the parameter is used as the reverse current threshold in mA. -1 is encoded as emuDcdcLnHighEfficiencyMode (EFM32 only).

◆ dcdcLnCompCtrl

EMU_DcdcLnCompCtrl_TypeDef EMU_DCDCInit_TypeDef::dcdcLnCompCtrl

DCDC Low-noise mode compensator control.
