Figure 6-2 SN8ICE 2K socket and jumper position
J1 : 7.5V DC power supply input.
J2 : Printer port socket. Connect to PC.
S1 : Power switch
S2 : Reset button. Press S2 resets the SN8ICE 2K. The program restarts from address 0.
D5 : FPGA(U7) successful configuration indicator
D6 : FPGA(12) successful configuration indicator
CON1 : Generic IO port, including all SN8P2xxx series I/O
JP1 : FPGA Test Pin, reserved for internal usage.
JP6 : IO expansion port, reserved for future usage
Power Jumper :
INTERNAL 5V : Short this jumper to provide 5V by SN8ICE 2K power circuit
AVREFH/VDD : AVREFH is the ADC high reference voltage. Short this jumper will connect
the AVREFH to VDD. Remove this jumper and connect external reference
