Configuration Flash Memory For Cyclone IV E - Military Grade?

Hi,

We do not have schematic or documentation for Cyclone IV but you may still follow the configuration connection based on Cyclone 10 LP (https://www.intel.com/content/dam/altera-www/global/en_US/support/boards-kits/cyclone10/c10lp-eval-a1-sch.PDF - page 4). The testing is not being tested on Cyclone IV as it is a old device but it should be possible.
