Does anyone know if it's guaranteed safe to apply a voltage to an analog input on a TMS32F0xxx if power is not present on the VDD and VDDA supply pins?  Our system monitors an independently powered external sensor.  It will routinely happen that the processor won't have power, but, the sensor will still be applying a voltage to an analog input.
