6.1.4.5. Combining JTAG and AS Configuration Schemes

You can combine the AS configuration scheme with the JTAG-based configuration.
This setup uses two 10-pin download cable headers on the board.
  • One download cable is used in JTAG mode to configure the Intel® Cyclone® 10 LP device directly through the JTAG interface.
  • The other download cable is used in AS mode to program the serial configuration device in-system through the AS programming interface.
If you try configuring the device using both schemes simultaneously, JTAG configuration takes precedence and AS configuration terminates.
