In this case, the standard peripheral circuit board cannot be used until the FPGA is erased and
reprogrammed.
• Erase time is about 2 minutes 40 seconds (max.) when the transfer rate between the ICE and PC is
38400 bps.
• Do not erase the sub FPGA unless otherwise specified, as it normally contains some LCD functions.
