However, you can configure the receive buffer size to meet your specific requirements, as shown in the below image:</P> <P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="2025-02-04_16-01-35.jpg" style="width: 999px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/322404i8471580EA1FF07F5/image-size/large?v=v2&amp;px=999" role="button" title="2025-02-04_16-01-35.jpg" alt="2025-02-04_16-01-35.jpg" /></span></P> <P>I recommend to trying the "<A href="https://community.nxp.com/t5/S32K-Knowledge-Base/Example-S32K312-UART-Transmit-amp-Receive-Using-Interrupt-DS3-5/ta-p/1818775" target="_blank" rel="noopener">Example S32K312 UART Transmit &amp; Receive Using Interrupt DS3.5 RTD300</A>" to&nbsp;familiarize yourself with the UART driver and APIs, which are useful to configure the Rx buffer to trigger the Rx_Full event with one character and access to the configured callback. Also, please refer to de S32K3XX Reference Manual Rev. 9 for more information about the LPUART module.</P> <P>Please let me know if this was helpful.</P> <P>- RomanVR.</P> Tue, 04 Feb 2025 22:05:45 GMT https://community.nxp.com/t5/S32K/S32K312-UART/m-p/2038053#M45621 RomanVR 2025-02-04T22:05:45Z
