Hi @1260784871 

The MU has 9 interrupt sources on each side. There are 1 general-purpose interrupt and 8 RX/TX interrupt sources.

The reset has a different function from the MU or system perspective. Please refer to section 39.3.3 Resets of S32K3xx Reference Manual, Rev. 5.

Hi @1260784871 

Setting the MUR bit to 1 and enabled with the MURIE bit resets both the MUA-side and MUB-side, forcing all control and status registers to return to their default values.

Hi @1260784871 

Sorry for the misunderstanding. It seems I am losing information due to the translation. Could you help me keep the conversation going in English?
