Max 10 Access in Stratix 10 DX

Hi,
purpose of the MAX10 system controller is described in user manual and becomes more obvious if you study the dev board schematics. It can be accessed via JTAG header, but you rarely want to modify or replace MAX10 content because you'd loose essential functions of the dev board, e.g. Stratix 10 USB JTAG programmer and configuration flash.
I presume the MAX10 design isn't disclosed by Terasic as for other dev boards. If you feel that you are missing necessary information about MAX10 operation, e.g. regarding configuration controller features for remote update, contact Terasic support. They are really helpful.
