The ConnectCore 9P family of modules critical timing requirement is the rise and fall
time of the input. If the rise time is too slow for the reset input, the hardware
strapping options may be registered incorrectly. If the rise time of a positive-edge-
triggered external interrupt is too slow, then an interrupt may be detected on both
the rising and falling edge of the input signal.
A maximum rise and fall time must be met to ensure that reset and edge sensitive
inputs are handled correctly. With Digi processors, the maximum is 500 nanoseconds
as shown:
On the ConnectCore 9P 9215 Development Board there was a measurement of 220ns
rise time and 10ns fall time.
