1 _{Maximum is highest voltage that POR is guaranteed.}
2 _{RAM will retain data down to POR voltage. RAM data not guaranteed to be valid following a POR.}
3 _{This parameter is characterized and not tested on each device.}
4 _{Measurement condition for pull resistors: VIn = VSS for pullup and VIn = VDD for pulldown.}
5 _{All functional non-supply pins are internally clamped to VSS and VDD.}
6 _{Input must be current limited to the value specified. To determine the value of the required current-limiting resistor, calculate}
resistance values for positive and negative clamp voltages, then use the larger of the two values.
