Description

Reset Management Unit (RMU) Peripheral API.

This module contains functions to control the RMU peripheral of Silicon Labs 32-bit MCUs and SoCs. RMU ensures correct reset operation and is responsible for connecting the different reset sources to the reset lines of the MCU or SoC.

Functions
void	RMU_ResetControl ( RMU_Reset_TypeDef reset, RMU_ResetMode_TypeDef mode)
	Disable/enable reset for various peripherals and signal sources.

void	RMU_ResetCauseClear (void)
	Clear the reset cause register.

uint32_t	RMU_ResetCauseGet (void)
	Get the cause of the last reset.

Macros
#define	RMU_LockupResetDisable (A) RMU_ResetControl ( rmuResetLockUp , A)
	RMU_LockupResetDisable kept for backwards compatibility.

Enumerations
enum	RMU_ResetMode_TypeDef { rmuResetModeClear = 0, rmuResetModeSet = 1 }
	RMU reset modes.

enum	RMU_Reset_TypeDef { rmuResetLockUp = _RMU_CTRL_LOCKUPRDIS_MASK }
	RMU controlled peripheral reset control and reset source control.

Function Documentation

◆ RMU_ResetControl()

void RMU_ResetControl	(	RMU_Reset_TypeDef	`reset,`
		RMU_ResetMode_TypeDef	`mode`
	)

Disable/enable reset for various peripherals and signal sources.

Parameters

[in]	`reset`	Reset types to enable/disable.s
[in]	`mode`	Reset mode.

◆ RMU_ResetCauseClear()

void RMU_ResetCauseClear ( void )

Clear the reset cause register.

This function clears all the reset cause bits of the RSTCAUSE register. The reset cause bits must be cleared by software before a new reset occurs. Otherwise, reset causes may accumulate. See RMU_ResetCauseGet() .

◆ RMU_ResetCauseGet()

uint32_t RMU_ResetCauseGet ( void )

Get the cause of the last reset.

To be useful, the reset cause must be cleared by software before a new reset occurs. Otherwise, reset causes may accumulate. See RMU_ResetCauseClear() . This function call will return the main cause for reset, which can be a bit mask (several causes) and clear away "noise".

Returns: A reset cause mask. See the reference manual for a description of the reset cause mask.

Macro Definition Documentation

◆ RMU_LockupResetDisable

#define RMU_LockupResetDisable ( A ) RMU_ResetControl ( rmuResetLockUp , A)

RMU_LockupResetDisable kept for backwards compatibility.

Enumeration Type Documentation

◆ RMU_ResetMode_TypeDef

enum RMU_ResetMode_TypeDef

RMU reset modes.

Enumerator
rmuResetModeClear	Reset mode clear.
rmuResetModeSet	Reset mode set.

◆ RMU_Reset_TypeDef

enum RMU_Reset_TypeDef

RMU controlled peripheral reset control and reset source control.

Enumerator
rmuResetLockUp	Cortex lockup reset select.
