POWER-UP RESET
The PALCE16V8 has been designed with the capability
to reset during system power-up. Following power-up,
all flip-flops will be reset to LOW. The output state will be
HIGH independent of the logic polarity. This feature pro-
vides extra flexibility 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
