POWER-UP RESET
The PALCE16V8 has been designed with the capability to reset during system power-up.
Following power-up, all ip-ops will be reset to LOW. The output state will be HIGH
independent of the logic polarity. This feature provides extra exibility to the designer and is
especially 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.
