Can you confirm this?</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="_Ferrari__0-1695823955216.png" style="width: 400px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/242966i39006436D95A8E54/image-size/medium?v=v2&amp;px=400" role="button" title="_Ferrari__0-1695823955216.png" alt="_Ferrari__0-1695823955216.png" /></span></P><P>&nbsp;</P><P>regards</P> Wed, 27 Sep 2023 14:12:58 GMT https://community.nxp.com/t5/Processor-Expert-Software/Instruction-set-of-LPC5526/m-p/1730593#M5716 _Ferrari_ 2023-09-27T14:12:58Z https://community.nxp.com/t5/Processor-Expert-Software/Instruction-set-of-LPC5526/m-p/1732217#M5718 <P class="lia-align-justify">Hello <a href="https://community.nxp.com/t5/user/viewprofilepage/user-id/202847">@_Ferrari_</a>&nbsp;,</P> <P class="lia-align-justify">On the LPC55S2x/LPC552x, the Cortex-M33 is used.
