RMU - Reset Management Unit
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
◆ RMU_ResetControl()
| void RMU_ResetControl | ( | RMU_Reset_TypeDef | reset, |
| RMU_ResetMode_TypeDef | mode |
||
| ) |
Disable/enable reset for various peripherals and signal sources.
- Parameters
-
[in] resetReset types to enable/disable.s [in] modeReset 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.
