Appendix A Electrical Characteristics
3 _{Measured with VIn = VSS.}
4 _{Measured with VIn = VDD.}
5 _{Power supply must maintain regulation within operating VDD range during instantaneous and operating maximum}
current conditions. If positive injection current (VIn > VDD) 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 clock rate is very low (which would reduce overall power
consumption).
6 _{All functional non-supply pins are internally clamped to VSS and VDD.}
7 _{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.
8 _{The RESET pin does not have a clamp diode to VDD. Do not drive this pin above VDD.}
