Notes:
1. These are test signals for factory use only and must be pulled up to OVdd for normal machine operation.
2. OVdd inputs supply power to the I/O drivers and Vdd inputs supply power to the processor core.
3. Internally tied to GND in the MPC740 CBGA package to indicate to the power supply that a low-voltage processor
is present. This signal is not a power supply input.
