Writing to RESETREAS during power-on reset will cause a bus fault.

I'm developing on the nRF54L15-DK using NCS3.1.1.
I've recently encountered a strange behavior.

My program writes to the RESETREAS register.
A bus fault sometimes occurs when starting up through a power-on reset.
However, when I press the reset button, writing to the RESETREAS register does not cause a bus fault.

What could be the cause of this?

Are you trying to clear the RESETREAS very early in boot or are you doing it in the main?

Are you using the helper functions or doing it directly? 

Can you give me a small sample to show this behavior on the DK?, sometimes write working and sometimes not working seems like a timing issue rather than access issue.

I'm sorry it was my mistake.
