You can refer to <A href="https://www.nxp.com/docs/en/user-guide/KLQRUG.pdf">this </A>document as this is also for a cortex M0+.&nbsp;</P><P></P><P>Please check the chapter 2.1.3.4.1 RESET_b and NMI_b for hardware recommendations, also there are some examples, that also disable it bye SW.</P><P></P><P>I believe the NMI might be the root cause of your issue; if this does not solve your issue, let me know.&nbsp;</P><P></P><P>Regards,&nbsp;</P><P>Estephania</P></BODY></HTML> Tue, 25 Dec 2018 23:56:56 GMT https://community.nxp.com/t5/Wireless-MCU/R41Z-module-does-freezing/m-p/828190#M5463 stephanie_m 2018-12-25T23:56:56Z
