1 _{Typical values are measured at 25°C. Characterized, not tested}
2 _{As the supply voltage rises, the LVD circuit will hold the MCU in reset until the supply has risen above VLVDL.}
3 _{Total Leakage current is the sum value for all GPIO pins; this leakage current is not distributed evenly across}
all pins but characterization data shows that individual pin leakage current maximums are less than 250 nA.
4 _{Measured with VIn = VDD.}
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.
