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.
Power supply must maintain regulation within operating V
conditions. If the positive injection current (V
result in external power supply going out of regulation. Ensure that external V
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).
Maximum is highest voltage that POR is guaranteed.
