(1) Operation outside the Absolute Maximum Ratings may cause permanent device damage. Absolute Maximum Ratings do not imply functional operation of the device at these or any other conditions beyond those listed under Recommended Operating Conditions. If outside the Recommended Operating Conditions but within the Absolute Maximum Ratings, the device may not be fully functional, and this may affect device reliability, functionality, performance, and shorten the device lifetime.

(2) The Absolute Maximum Ratings for (TS1–VSS) apply after the device completes POR and should be observed after t_BOOTREADY (10 ms), following the application of the boot signal on TS1. Prior to completion of POR, TS1 should not exceed 5 V.
