Summary:Various embodiments of the invention provide a method for transferring communication data through one or more pins of a programmable logic device (PLD). The PLD includes a configuration port that may be used to program programmable logic and interconnect resources of the PLD. The programmable logic and interconnect resources include the input/output blocks of the PLD. Portions of the communication data are sequentially transferring between certain pins of the PLD and certain input/output registers in one or more input/output blocks associated with the pins. A frame of configuration data including a portion of the communication data is transferred between the input/output registers and a frame register of the configuration port of the PLD. Formats are converted between the portion of the communication data and the frame of the configuration data in the frame register of the PLD.
