Currently I use mc9s12xdt512 controller.
I need to have different power supply for "regulator power input" and "I/O supply"
The solution would be as follow:
VDDR (Regulator power input) 3.3V
VDDA (Analog power supply) 5V
VDDX (I/O supply) 5V
VRH (Reference voltage) 5V.
Is it possible for the chip to work under this condition?
