This flip flop sets its output according to the set (S) or reset (R) input lines. If the set line is set, the output gets set. If the reset line is set, the output gets reset. If no line is set, the output stays unchanged. | This flip flop sets its output according to the set (S) or reset (R) input lines. If the set line is set, the output gets set. If the reset line is set, the output gets reset. If no line is set, the output stays unchanged. For the special case where set and reset lines are both set, two types of RS flip flops exist: for the RS flip flop (<type>RS</type>), the reset line is dominant and the output is reset. Alternatively, a SR flip flop (<type>SR</type>) has a dominant set line and the output gets set if set and reset line are set. | ||
