1 _{Input must be current limited to the value specified. To determine the value of the required}
current-limiting resistor, calculate resistance values for positive (V_DD) and negative (V_SS) clamp
voltages, then use the larger of the two resistance values.
2 _{All functional non-supply pins are internally clamped to VSS and VDD.}
3 _{Power supply must maintain regulation within operating VDD range during instantaneous and}
operating maximum current conditions. If positive injection current (V_In > V_DD) is greater than
I_DD, the injection current may flow out of V_DD and could result in external power supply going
out of regulation. Ensure external V_DD load will shunt current greater than maximum injection
current. This will be the greatest risk when the MCU is not consuming power. Examples are: if
no system clock is present, or if the clock rate is very low which would reduce overall power
consumption.
