P11 Connector Pin Assignments

Programming Support for Expansion Boards

Programming expansion board is done using the GXFPGA registers and memory access functions. In addition a GxFpgaSetExpansionBoardBypass can be used to direct the I/O banks to the expansion board. The GxFpgaGetExpansionBoardID can also be used to detect the installed expansion board ID. The expansion board ID is read from P8 pins 19, 21, 23 and 25 to form a 4 bit integer (0-15).
