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 { rmuResetModeDisabled = 0, rmuResetModeEnabled = 1 }
	RMU reset modes.

enum	RMU_Reset_TypeDef { rmuResetWdog0 = _EMU_RSTCTRL_WDOG0RMODE_MASK, rmuResetSys = _EMU_RSTCTRL_SYSRMODE_MASK, rmuResetCoreLockup = _EMU_RSTCTRL_LOCKUPRMODE_MASK, rmuResetAVDD = _EMU_RSTCTRL_AVDDBODRMODE_MASK, rmuResetIOVDD0 = _EMU_RSTCTRL_IOVDD0BODRMODE_MASK, rmuResetDecouple = _EMU_RSTCTRL_DECBODRMODE_MASK, rmuResetDCI = _EMU_RSTCTRL_DCIRMODE_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
rmuResetModeDisabled	Reset mode disabled.
rmuResetModeEnabled	Reset mode enabled.

◆ RMU_Reset_TypeDef

enum RMU_Reset_TypeDef

RMU controlled peripheral reset control and reset source control.

Enumerator
rmuResetWdog0	WDOG0 reset select.
rmuResetSys	SYSRESET select.
rmuResetCoreLockup	Cortex lockup reset select.
rmuResetAVDD	AVDD monitoring select.
rmuResetIOVDD0	IOVDD0 monitoring select.
rmuResetDecouple	Decouple monitoring select.
rmuResetDCI	DCI reset select.
