1. I 2 C Fm+ is only supported for V DD above 2.7V.

This bit field controls the pin configuration of the Reset pin.

Stresses beyond those listed in this section can cause permanent damage to the device. This is a stress rating only. Functional operation of the device at these or other conditions beyond those indicated in the operational sections of this specification, is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

Table 37-1. Absolute Maximum Ratings

1. The maximum current rating requires even load distribution across I/O pins. The maximum current rating may be limited by the device package power dissipation characterizations. See 37.9 Thermal Specifications to calculate device specifications.
2. Power dissipation is calculated as follows: P DIS = VDD x {I DD - Σ I OH} + Σ {(V DD - V OH) x I OH} + Σ (VOI x IOL)
