power-up reset

Following power up, all registers are reset to zero. The output level depends on the polarity selected during

programming. This feature provides extra flexibility to the system designer and is especially valuable in

monotonic. Following power-up reset, a low-to-high clock transition must not occur until all applicable input and

feedback setup times are met.
