Appendix A Electrical Characteristics

7 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 IDD, the injection current may flow out of VDD and could result

in external power supply going out of regulation. Ensure external VDD 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).
