Description

Energy Management Unit (EMU) Peripheral API.

This module contains functions to control the EMU peripheral of Silicon Labs 32-bit MCUs and SoCs. The EMU handles the different low energy modes in Silicon Labs microcontrollers.

Data Structures
struct	EMU_EM23Init_TypeDef
	EM2 and 3 initialization structure.

struct	EMU_EM4Init_TypeDef
	EM4 initialization structure.

struct	EMU_BUPDInit_TypeDef
	Backup Power Domain Initialization structure.

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

void	EMU_EM23PresleepHook (void)
	Energy mode 2/3 pre-sleep hook function.

void	EMU_EM23PostsleepHook (void)
	Energy mode 2/3 post-sleep hook function.

void	EMU_EM4Init (const EMU_EM4Init_TypeDef *em4Init)
	Update the EMU module with Energy Mode 4 configuration.

void	EMU_EnterEM2 (bool restore)
	Enter energy mode 2 (EM2).

void	EMU_EnterEM3 (bool restore)
	Enter energy mode 3 (EM3).

void	EMU_Save (void)
	Save the CMU HF clock select state, oscillator enable, and voltage scaling (if available) before EMU_EnterEM2() or EMU_EnterEM3() are called with the restore parameter set to false.

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.

void	EMU_EM4PresleepHook (void)
	Energy mode 4 pre-sleep hook function.

void	EMU_EnterEM4 (void)
	Enter energy mode 4 (EM4).

void	EMU_MemPwrDown (uint32_t blocks)
	Power down memory block.

void	EMU_RamPowerDown (uint32_t start, uint32_t end)
	Power down RAM memory blocks.

void	EMU_RamPowerUp (void)
	Power up all available RAM memory blocks.

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

void	EMU_BUPDInit (const EMU_BUPDInit_TypeDef *bupdInit)
	Configure Backup Power Domain settings.

void	EMU_BUThresholdSet ( EMU_BODMode_TypeDef mode, uint32_t value)
	Configure the Backup Power Domain BOD Threshold value.

void	EMU_BUThresRangeSet ( EMU_BODMode_TypeDef mode, uint32_t value)
	Configure the Backup Power Domain BOD Threshold Range.

void	EMU_BUStatEnSet (bool enable)
	Enable backup mode status export.

void	EMU_BUEnableSet (bool enable)
	Enable backup mode.
