Electrical characteristics
3.8.1.2
In the external regulation mode, the core supply is provided externally using a switched regulator. This saves on-chip power
consumption by avoiding the voltage drop over the ballast transistor. The external supply mode is selected via a board level
supply change at the V
3.8.1.3
For MPC5604E, the external supplies need to be maintained as per the following relations:
