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#
RMU controlled peripheral reset control and reset source control.
Functions#
Disable/enable reset for various peripherals and signal sources.
Clear the reset cause register.
Get the cause of the last reset.
Macros#
RMU_LockupResetDisable kept for backwards compatibility.

RMU_ResetCauseClear#
void RMU_ResetCauseClear (void )
Clear the reset cause register.
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().

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