It is a part of Flash IFR which can be<BR />used to store non-volatile data.<BR />The global memory from 0x0_4000 is accessible when we set NVMRES bit<BR />(MMCCTL1=0x01;) at PPAGE 0x01 and memory window 0x8000~0xBFFF.</P><P></P><P>See&nbsp;Table 24-5. Program IFR Fields in the <A href="https://www.nxp.com/docs/en/data-sheet/MC9S12GRMV1.pdf">reference manual</A>.&nbsp;<BR />Programming the own serial number is possible into Program Once Field - 64B<BR />at global address 0x0_40C0 – 0x0_40FF.</P><P></P><P>The additional useful information you can find in this thread:<BR /> <A _jive_internal="true" class="link-titled" href="https://community.nxp.com/message/869910?commentID=869910#comment-869910" title="https://community.nxp.com/message/869910?commentID=869910#comment-869910">https://community.nxp.com/message/869910?commentID=869910#comment-869910</A>&nbsp;</P><P></P><P>I hope it helps you.</P><P></P><P>Best regards,</P><P>Diana</P></BODY></HTML> Thu, 12 Jul 2018 07:51:28 GMT https://community.nxp.com/t5/S12-MagniV-Microcontrollers/G48-Mass-production/m-p/843227#M16029 dianabatrlova 2018-07-12T07:51:28Z
