1 _{Typicals are measured at 25°C.}
2 _{This parameter is characterized and not tested on each device.}
3 _{Measurement condition for pull resistors: VIn = VSS for pullup and VIn = VDD for pulldown.}
4 _{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 clock rate is very low which would reduce overall power consumption.
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.
7 _{This parameter is characterized and not tested on each device.}
8 _{IRQ does not have a clamp diode to VDD. Do not drive IRQ above VDD.}
