Figure 2-10-1 is the CON1 connector on core board, and the pin1 of connector is
marked on the board.
CON2 Connector
The 80-Pin connector CON2 is used to extend the IOs of FPGA bank13 and
bank14, the voltage level of these IOs are +3.3V standard. The pin assignment of the
CON2 connector is shown in table 2-10-2：
