A.3.6. General Purpose Control and Status Register (Offset 0x30)

This register provides up to eight I/O pins each for Application Layer Control and Status requirements. This feature supports Partial Reconfiguration of the FPGA fabric. Partial Reconfiguration only requires one input pin and one output pin. The other seven I/Os make this interface extensible.
