Input/Output Pins
The digital input stage of the shared analog/digital input pins is identical to the input
stage of the standard digital input/output pins.
Note: These parameters are not subject to production test, but verified by design and/or
characterization.

1) Current required to override the pull device with the opposite logic level (“force current”).
With active pull device, at load currents between force and keep current the input state is undefined.
2) Load current at which the pull device still maintains the valid logic level (“keep current”).
With active pull device, at load currents between force and keep current the input state is undefined.
3) Hysteresis is implemented to avoid metastable states and switching due to internal ground bounce. It can not
be guaranteed that it suppresses switching due to external system noise.
