Circuitry within the GAL22V10 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 asyn-
chronous nature of system power-up, some conditions must be
met to provide a valid power-up reset of the GAL22V10. 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 normal sys-
tem operation, avoid clocking the device until all input and feed-
back path setup times have been met. The clock must also meet
the minimum pulse width requirements.
