Greetings.
Data sheet Section 7.1.1 Input Timings, state that the maximum t(in_slew) is 1nS. I would like clarification on this.
Does this mean that all logic input signals going into the controller must have a 1nS rise/fall time or faster? That would seem very fast. Standard LVC logic typically has a rise/fall time of 4nS.
Or, is this 1 nS criteria congruent with the minimum pulse width also shown in section 7.1.1? If so then:
What would be the required t(in_slew) for I/O pins, particularly interrupt driven pins?
Best Regards, Charlie
