I would like to know if the transmitter is in flow controlled ON/OFF. From the register list (Uart), the modem signal state are not listed. It is not mention if GPIO input is still valid if the pin is in Uart mode.</P><P>Thanks, Guy</P> Tue, 15 Dec 2020 12:06:33 GMT https://community.nxp.com/t5/S32K/S32K-Uart-CTS-B-Input-State/m-p/1199636#M9258 guys_fr 2020-12-15T12:06:33Z https://community.nxp.com/t5/S32K/S32K-Uart-CTS-B-Input-State/m-p/1200214#M9273 <P>Hi&nbsp;guysansoucy,</P> <P>Whenever a pin is configured in any digital pin muxing mode, the input buffer for that pin is enabled allowing the pin state to be read via the corresponding GPIO Port Data Input Register (<STRONG>GPIO_PDIR</STRONG>).</P> <P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="pin state to be read.png" style="width: 999px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/132818iB49FF623390AA992/image-size/large?v=v2&amp;px=999" role="button" title="pin state to be read.png" alt="pin state to be read.png" /><span class="lia-inline-image-caption" onclick="event.preventDefault();">pin state to be read.png</span></span><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Figure 4-1.
