(page 334).</SPAN><BR /><BR /><SPAN>I.e. it will generate DIVADDVAL = 1 and DLL = 2, which ends up breaking RX (interestingly it still generates the correct TX baud).&nbsp; Try inputting the value of 2291667 for example.&nbsp; It is possible to generate this baud (DLL = 3, DIVADDVAL =1 and MULADDVAL =11)...</SPAN></BODY></HTML> Wed, 15 Jun 2016 17:49:35 GMT https://community.nxp.com/t5/LPC-Microcontrollers/Bug-in-IP-UART-SetBaud/m-p/521423#M4184 lpcware 2016-06-15T17:49:35Z Re: Bug in IP_UART_SetBaud https://community.nxp.com/t5/LPC-Microcontrollers/Bug-in-IP-UART-SetBaud/m-p/521424#M4185 <HTML><HEAD></HEAD><BODY><STRONG>Content originally posted in LPCWare by xianghuiwang on Sat Sep 21 17:33:00 MST 2013</STRONG><BR /><SPAN>Hi, </SPAN><BR /><SPAN>good catch, we will correct the driver.
