Abstract
A circuit for processing data in an integrated circuit device comprises a selection circuit; a first register coupled to a first output of the selection circuit; a second register implemented as a latch and coupled to a second output of the selection circuit; and a signal line coupled between the output of the first register and an input of the selection circuit. The selection circuit enables the coupling of an output signal of the first register to an input of the second register. A method of processing data in an integrated circuit device is also disclosed.
