11.4 Inputs and Outputs
Specifications are valid for –40 °C  T
except where noted. Unless otherwise specified, all charts and graphs show typical values.
When the power supplies ramp up, there are low-impedance connections between each GPIO pin and its V
the pin voltages to track V
low-impedance connections no longer exist and the pins change to their normal NVL settings.
