Hi everybody,

I'm using an LPCU68 in a particular circuit. In the circuit I use two different supply sources and I turn off the micro in order to go in “power-saving” state (another micro is connected to another suplly and it's always on).
When the LPC is turned off, are all the pins in a not-well-known state? I mean, can some pin be in a high or low logical state with low impedance and draw-source some current?
Is it possible to have all of these in high impedance state?

Best regards
