asynchronous nature of system power-up, some conditions must
be met to provide a valid power-up reset of the ispGAL22V10.
First, the Vcc rise must be monotonic. Second, the clock input
must be at static TTL level as shown in the diagram during power
up. The registers will reset within a maximum of
tpr time. As in nor-
mal system operation, avoid clocking the device until all input and
feedback path setup times have been met. The clock must also
meet the minimum pulse width requirements.

INPUT/OUTPUT EQUIVALENT SCHEMATICS
Circuitry within the ispGAL22V10 provides a reset signal to all reg-
isters during power-up. All internal registers will have their Q out-
puts set low after a specified time (tpr, 1
μ
s MAX). As a result, the
state on the registered output pins (if they are enabled) will be
either high or low on power-up, depending on the programmed
polarity of the output pins. This feature can greatly simplify state
machine design by providing a known state on power-up. The
timing diagram for power-up is shown below. Because of the
