ABSTRACT:
A programmable logic device (PLD) data transfer cable includes a parallel interface, a programming interface, and a logic control circuit. The parallel interface is used for connecting to PLDs. The logic control circuit includes a first group of transmission channels, a second group of transmission channels, a first group of switches, and a second group of switches. The first and second group of switches control the working status of the first and second group of transmission channels respectively. The electrical connections between pins of the parallel interface and the programming interface when first group of transmission channels are activated are different with those when second group of transmission channels are activated.
