    Yes.  On the eZdspF2812 board, there is an external SRAM connected to XZCS6AND7n which allows you to read and write via XINTF Zone 6 (and XINTF Zone 7 if XMP/MCn=1).

    There should not be hardware setting for XINTF zone 6.  There is for XINTF zone 7, as mentioned above.  The TMS320x281x External Interface (XINTF) Reference Guide (Rev. C) mentions this and illustrates the zones in Figure 1.

     

    Furthermore, you should also use the C281x C/C++ Header Files and Peripheral Examples as this provides useful examples that can run on the eZdspF2812 board.  These header files can be used in your application to help in writing to the peripheral registers, etc.
