Pin 116 (or P2_1) is used as USB enable for USB1. We are using UBS 1 as mass storage host. Since P2_1 is also GPIO 5 bit 1 we are configuring through the control register SFSP2_1 (0x40086104). The document talks about different modes (Function 0, Function 1 etc.)&nbsp; The sample code we found ( from NXPUSBLib) mentions that we need to configure that pin as Function 4 for USB. However, I am not finding any document that explains what is function 4 (or any other function for that matter). Is there any document that explains different GPIO functions? Is there document that explains different register setting for USB 1 (everything in one place)?</P><P>Thanks</P></BODY></HTML> Wed, 20 Feb 2019 20:05:05 GMT https://community.nxp.com/t5/LPC-Microcontrollers/GPIO-mode-setting-for-USB-in-LPC4357/m-p/880223#M35167 ssudhir 2019-02-20T20:05:05Z Re: GPIO mode setting for USB in LPC4357 https://community.nxp.com/t5/LPC-Microcontrollers/GPIO-mode-setting-for-USB-in-LPC4357/m-p/880224#M35168 <HTML><HEAD></HEAD><BODY><P>Hello ,</P><P>Could you please tell me which document you&nbsp; refer to.</P><P>About the pins function, Check the User manual of LPC4357 processor, Table 189 Pin multiplexing:</P><P><span class="lia-inline-image-display-wrapper" image-alt="pastedImage_14.png"><img src="https://community.nxp.com/t5/image/serverpage/image-id/77204i6B14B6FEEDA348C9/image-size/large?v=v2&amp;px=999" role="button" title="pastedImage_14.png" alt="pastedImage_14.png" /></span></P><P></P><P></P><P><BR />Have a great day,<BR />TIC</P><P></P><P>-------------------------------------------------------------------------------<BR />Note:<BR />- If this post answers your question, please click the "Mark Correct" button.
