But I think KM35 is similar to it.</P> <P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="jingpan_0-1624437655937.png" style="width: 490px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/147764i293B8F516D368387/image-dimensions/490x354?v=v2" width="490" height="354" role="button" title="jingpan_0-1624437655937.png" alt="jingpan_0-1624437655937.png" /></span></P> <P>&nbsp;</P> <P>2. The functions apply across all digital pin muxing modes and individual peripherals do not override the configuration in the Pin Control register. For example, if an I2C function is enabled on a pin, that does not override the pullup or open drain configuration for that pin.</P> <P>&nbsp;</P> <P>Regards,</P> <P>Jing</P> <P>&nbsp;</P> Wed, 23 Jun 2021 08:42:13 GMT jingpan 2021-06-23T08:42:13Z https://community.nxp.com/t5/Kinetis-Microcontrollers/KM35-PORT-STRUCTURE/m-p/1292895#M60858 <P>&nbsp;</P><P>Hi.</P><P>The KE04 Sub-Family Reference Manual describes the structure of the port, but the Kinetis KM35 Sub-Family Reference Manual does not seem to.<BR />1. Is there any material for the port structure of KM35?<BR />2. When using the KM35 port with UART, does the open drain setting also work?</P><P>&nbsp;</P><P>thanks.</P><P>&nbsp;</P> Wed, 16 Jun 2021 03:05:05 GMT https://community.nxp.com/t5/Kinetis-Microcontrollers/KM35-PORT-STRUCTURE/m-p/1292895#M60858 jun1 2021-06-16T03:05:05Z https://community.nxp.com/t5/Kinetis-Microcontrollers/KM35-PORT-STRUCTURE/m-p/1296716#M60914 <P>Hi jun,</P> <P>1.
