ByteBlaster Connections
ByteBlaster cable 25-pin male header that connects parallel port, 10-pin female plug that connects circuit board. Data downloaded from parallel port through ByteBlaster download cable circuit board connections discussed this section. configure/program 3.3-V devices (e.g., FLEX 10KA 7000A devices) using ByteBlaster cable, connect 5.0-V power supply device 3.3-V power supply. FLEX 10KA 7000A devices have 5.0-V tolerant inputs, ByteBlaster 5.0-V output will harm these 3.0-V devices. pull-up resistors should connected 5.0-V power supply.
