A programmable logic device (PLD) includes programmable logic circuitry
and a bridge circuitry. The bridge circuitry includes a first interface
circuitry and a first signal select circuitry. The first signal select
circuitry couples to the first interface circuitry and the programmable
logic circuitry. The bridge circuitry further includes an information
interchange circuitry. The first signal select circuitry is configured to
selectably provide a communication path between the information
interchange circuitry and either the programmable logic circuitry or the
first interface circuitry.
