Notes:  
1. These are test signals for factory use only and must be pulled up to OVdd for normal machine opera-  
tion.  
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 PID-8t PPC750 360 CBGA package to indicate to the power supply  
that a 2.5v core voltage processor is present. Future lower core voltage processors may tie this pin  
internally to GND. CAUTION: this is different from the 255 CBGA package. This is NOT a supply pin.  
4. These pins are reserved for potential future use as additional L2 address pins.
