Push-Button Switches
Board reference S9 is the CPU reset push-button switch, CPU_RESETn, which is an
input to the Stratix IV GT device. The CPU_RESETn is intended to be the master reset
signal for the FPGA design loaded into the Stratix IV GT device. The CPU_RESETn
signal must be enabled within the Quartus II software for this reset function to work.
Otherwise, the CPU_RESETn acts as a regular I/O pin. When enabled in the Quartus
II software, and then set to logic 1 on the board, this switch resets every register
within the FPGA.
