Hi roffez,


I apologize for overlooking your post. If you plan to utilize JTAG, the handbook specifies that for JTAG-based configuration schemes, the MSEL pin settings are disregarded. It is crucial not to leave the MSEL pins floating; instead, connect them to Vcca or GND. These pins support the non-JTAG configuration scheme employed in production. Intel advises connecting the MSEL pins to GND if your device exclusively uses JTAG configuration. You can locate this information on page 145 of the handbook, accessible here: [https://www.intel.com/programmable/technical-pdfs/683777.pdf]. Additionally, you may refer to this Knowledge Database (KDB) article for further clarification: [https://www.intel.com/content/www/us/en/support/programmable/articles/000081511.html].


Regards,

Fakhrul
