The document below says the systemace chip has no connection on pin 79.

And NC pins must  not be connected to any signals.

http://www.xilinx.com/support/documentation/data_sheets/ds080.pdf

 

But int the board schematics such as ML401,  pin79(noted as CFGPROG) is connected to PROGRAM_B pin of the FPGA.

 

What is functionality of pin 79 in System ACE controller chip?

 

Is it output or input? 

 

Kudos!
