1) Hysteresis is implemented to avoid metastable states and switching due to internal ground bounce. It can't be guaranteed that
it suppresses switching due to external system noise.
2) Values for Pull-up resistor is defined via parameter RMDU in table VADC 5V.
3) Values for Pull-down resistor is defined via parameter RMDD in table VADC 5V.
