 Set Reset flip-flop.


 The SR flip-flops hold on a leading edge on the
 set-signal and reset on a leading edge on the
 res(et)-signal.

 If both the set and reset signals are TRUE at the same
 time the state of the flip-flops is undefined. At this
 condition is a
  - SR_S flip_flop TRUE ( = Set)
  - SR_R flip_flop FALSE ( = Reset)
