power-up reset (see Figure 2)
Following power up, all registers are reset to zero. This feature provides extra flexibility to the system designer
and is especially valuable in simplifying state-machine initialization. To ensure a valid power-up reset, it is
important that the rise of VCC be monotonic. Following power-up reset, a low-to-high clock transition must not
occur until all applicable input and feedback setup times are met.
