Is programming it this way possible?&nbsp; Most of the reference designs I have seen or read about suggest that DBGEN should be pulled high.&nbsp; I appreciate any pointers, guidance, or comments.</SPAN><BR /><SPAN>Thanks!</SPAN></BODY></HTML> Wed, 15 Jun 2016 18:53:25 GMT https://community.nxp.com/t5/LPC-Microcontrollers/Programming-an-LPC4337-thru-JTAG-interface/m-p/569278#M17913 lpcware 2016-06-15T18:53:25Z Re: Programming an LPC4337 thru JTAG interface. https://community.nxp.com/t5/LPC-Microcontrollers/Programming-an-LPC4337-thru-JTAG-interface/m-p/569279#M17914 <HTML><HEAD></HEAD><BODY><STRONG>Content originally posted in LPCWare by embd02161991 on Thu Apr 30 16:27:56 MST 2015</STRONG><BR /><SPAN>Hi,</SPAN><BR /><BR /><SPAN>In LPC43xx devices, when the DBGEN pin is HIGH, the ARM debug mode is entered.
