1. Typical values are based on characterization data at V_DD = 5.0 V, 25 °C unless otherwise stated.
2. This is the shortest pulse that is guaranteed to be recognized as a reset pin request.
3. To enter BDM mode following a POR, BKGD/MS must be held low during the powerup_ and for a_hold time of t_MSH after
V_DD rises above V_LVD.
4. Timing is shown with respect to 20% V_DD and 80% V_DD levels. Temperature range -40 °C to 105 °C.
