(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(1) MISC pins sampled at de-assertion of GRSTz: BATEN[4:1], SMBUSz, and PWRCTL_POL.
(2) There is no power-on relationship between VDD33 and VDD unless GRSTz is only connected to a capacitor to GND. Then VDD must be stable minimum of 10 µs before the VDD33.
(3) An active reset is required if the VDD33 supply is stable before the VDD11 supply. This active Reset shall meet the 3ms power-up delay counting from both power supplies being stable to the de-assertion of GRSTz.
