Is PROGRAMN pin independent of JTAG programming operations?SupportArticlePage13f40cde-d1bd-43be-be7c-f466e71abd02FAQ/Support/AnswerDatabase/1/3/2/1323https://edge.sitecorecloud.io/latticesemi9e32-latticesemi06bb-prod9ecc-d341/media/Project/Lattice/LatticeSemi/Images/SearchThumbnails/FAQ.png?sc_lang=enThe PROGRAMN pin does not affect the JTAG state machine or boundary scan cells. However, the PROGRAMN pin does clear the SRAM configuration memory of the device. Because of this, a logic low signal on PROGRAMN pin at any time during JTAG configuration process may result in a failure due to the SRAM cells being cleared independent of the configuration process. Therefore it is important that the PROGRAMN pin is held at logic high during the configuration process.
