It happened rarely but it confuses me really</SPAN>&nbsp;could you please me tell why would it happen.</P> Wed, 26 Apr 2023 10:54:59 GMT SYP 2023-04-26T10:54:59Z https://community.nxp.com/t5/S32K/S32k148/m-p/1640507#M22402 <P>Hello sir, can I ask for some support.</P><P>&nbsp; I got some problem, when I use S32K148 on a item, it gose wrong&nbsp; and the phenomenon is that when trigger the software reset, the reset pin continues to pull down <SPAN>sporadicly.
