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 L2OVDD in the MPC750 CBGA package to indicate the power present at the L2 cache interface.
This signal is not a power supply input.
Caution: This is different from the MPC740 CBGA package.
4. These pins are reserved for potential future use as additional L2 address pins.
