RMUEMLIB
Detailed 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.

Function Documentation
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().

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.
