A first sequence state storage module (20) periodically stores a present
state (22) of a long code generator (30). Following a restoration
of power after a power cut condition, or following the termination of any other
interruption of the generation of the long code, a sequence recovery module (50)
then provides an updated present state (36). The updated present state (36)
is based upon a stored present state (24) and a time value (52) that
is reset whenever the present state (22) of the long code or other sequence
is stored and that is available even when the long code or other sequence is interrupted.
