Output Driver Characteristics
This table provides information on the characteristics of the output driver strengths. The values are preliminary estimates.

Power Sequencing
The device requires its power rails to be applied in a specific sequence in order to ensure proper device operation. During the
power ramp up, before the power supplies are stable and if the I/O voltages are supplied before the core voltage, there may be
