However, I'd like to have this setting saved as non-volatile. As a result, I'm wondering if this setting could be saved permanently (e.g. through fuses) and if it's possible, how to do it?</P><P></P><P>Thanks!</P></BODY></HTML> Tue, 30 May 2017 23:00:27 GMT https://community.nxp.com/t5/i-MX-Processors/Non-volatile-setting-for-SNVS-LP-register/m-p/668151#M102790 keithmo 2017-05-30T23:00:27Z Re: Non-volatile setting for SNVS_LP register https://community.nxp.com/t5/i-MX-Processors/Non-volatile-setting-for-SNVS-LP-register/m-p/668152#M102791 <HTML><HEAD></HEAD><BODY><P>Hi Keith</P><P></P><P>SNVS_LP registers are retained when provided SNVS_IN voltage,</P><P>I am afraid there is no special fuse for that.
