2
This is the shortest pulse that is guaranteed to be recognized as a reset or interrupt pin request. Shorter pulses are not
guaranteed to override reset requests from internal sources.
3
To enter BDM mode following a POR, BKGD/MS should be held low during the power-up and for a hold time of t

This is the minimum assertion time in which the interrupt
may
be recognized. The correct protocol is to assert the interrupt
request until it is explicitly negated by the interrupt service routine.
