5 V / 3.3 V switchable Pads
Pad classes slow GPIO and fast GPIO support both Automotive Level (AL) or TTL level (TTL) operation.
Parameters are defined for AL operation and degrade in TTL operation.

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-down resistor is defined via parameter RMDD in table VADC 5V.
