For example, let's take the USART driver. How does it generate the clock frequency using the internal oscillator or an external oscillator? just explain those stop using this clock generation diagram</SPAN></P><P>&nbsp;</P> Mon, 20 May 2024 06:14:22 GMT https://community.nxp.com/t5/LPC-Microcontrollers/LPC865M201JHI48-Clock-Generation-Diagram-Doubt/m-p/1868596#M56092 BerlinRaj 2024-05-20T06:14:22Z https://community.nxp.com/t5/LPC-Microcontrollers/LPC865M201JHI48-Clock-Generation-Diagram-Doubt/m-p/1868749#M56094 <P>Hello&nbsp;<a href="https://community.nxp.com/t5/user/viewprofilepage/user-id/223867">@BerlinRaj</a>&nbsp;</P> <P>About the clock generation, recommend you check Clock configuration in MCUXpresso IDE.</P> <P>Can also config clock through it.</P> <P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Alice_Yang_1-1716195844742.png" style="width: 400px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/279593i766F46A601AC3F24/image-size/medium?v=v2&amp;px=400" role="button" title="Alice_Yang_1-1716195844742.png" alt="Alice_Yang_1-1716195844742.png" /></span></P> <P>&nbsp;</P> <P>&nbsp;</P> <P>BR</P> <P>Alice</P> <P>&nbsp;</P> Mon, 20 May 2024 09:04:42 GMT https://community.nxp.com/t5/LPC-Microcontrollers/LPC865M201JHI48-Clock-Generation-Diagram-Doubt/m-p/1868749#M56094 Alice_Yang 2024-05-20T09:04:42Z
