(1)
The pulse width given is sufficient to generate a CPU interrupt. However, if a user wants to have the device recognize the GP[x] input
changes through software polling of the GPIO register, the GP[x] input duration must be extended to allow device enough time to access
the GPIO register through the internal bus.
