15.6.11. Set-Priority Latch (SRlatch)

DSP Builder offers two single-cycle latency latch subsystems for common operations for the valid signal, latching with set and reset. The SRlatch block gives priority to the reset input signal. The SRlatch_PS block gives priority to the set input signal. In both blocks if set and reset inputs are both zero the current output state is maintained.
