RMU - Reset Management Unit#

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.

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.

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.

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.

Parameters
N/A

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().


Definition at line 276 of file platform/emlib/src/em_rmu.c

RMU_ResetCauseGet#

uint32_t RMU_ResetCauseGet (void )

Get the cause of the last reset.

Parameters
N/A

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.
