Abstract
A method for operating a master latch and a slave latch coupled to the master latch includes the steps of attempting to operate the master latch and the slave latch in a first mode in which (1) the master latch is held in an open condition; and (2) the slave latch is pulsed so as to latch data passed through the open master latch. If the master latch and the slave latch do not operate in the first mode, the master latch and the slave latch are operated in a second mode in which (1) a first clock signal is employed to latch data with the master latch; and (2) a second clock signal is employed to latch data latched by the master latch with the slave latch.
