POWER-UP RESET
The power-up reset feature ensures that all flip-flops will be reset to
LOW after the device has been powered up. The output state will
depend on the programmed pattern. This feature is valuable in
simplifying state machine initialization. A timing diagram and
parameter table are shown below. Due to the synchronous operation
of the power-up reset and the wide range of ways V
CC
can rise to its
steady state, two conditions are required to ensure a valid power-up
reset. These conditions are:
1. The V
CC
rise must be monotonic.
2. Following reset, the clock input must not be driven from LOW to
HIGH until all applicable input and feedback setup times are met.
