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.
