That's why you can't see document and demo code on this usage.</P> <P>For LPC551X/S1x, the supported Block Diagram is as below:</P> <P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="ZhangJennie_0-1638775728924.png" style="width: 400px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/164150i6194079FFAF73505/image-size/medium?v=v2&amp;px=400" role="button" title="ZhangJennie_0-1638775728924.png" alt="ZhangJennie_0-1638775728924.png" /></span></P> <P>Hope this helps,</P> <P>Jun Zhang</P> <P>&nbsp;</P> Mon, 06 Dec 2021 07:30:21 GMT https://community.nxp.com/t5/LPC-Microcontrollers/SD-CARD-connection-to-LPC55S14/m-p/1381745#M47261 ZhangJennie 2021-12-06T07:30:21Z
