1 Typical values are based on characterization data at V
DD = 3.3 V, 25 °C unless otherwise stated.
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
MSH after VDD
rises above VLVD.
4 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.
5 Timing is shown with respect to 20% V
DD and 80% VDD levels. Temperature range –40 °C to 85 °C.
