POWER-UP RESET
The power-up reset feature ensures that all ip-ops 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 VCC can rise
to its steady state, two conditions are required to ensure a valid power-up reset. These conditions
are:
x
The VCC rise must be monotonic.
x
Following reset, the clock input must not be driven from LOW to HIGH until all applicable input
and feedback setup times are met.
