Note:
1. These are test signals for factory use only and must be pulled up to OV
DD
for normal machine operation.
2. OV
DD
inputs supply power to the I/O drivers and V
DD
inputs supply power to the processor core.
3. Internally tied to L2OV
DD
in the PID8p-750 360 CBGA package. This is NOT a supply pin.
4. These pins are reserved for potential future use as additional L2 address pins.
5. Pull up and pull down resistor requirements for all pins are listed in the “Pull-up / Pull-down Resistor Requirements” section on page 33
6. BVSEL selects the I/O voltage on the 60X bus. L2VSEL selects the I/O voltage on the L2 bus. Please refer to the Table “Recommended Operating
Conditions1,2,3,” on page 6, for the use of these pins.
7. TCK must be tied high or low for normal machine operation.
8. Address and data parity signals must be tied high or low if unused in the design.
9. Starting with rev levels dd3.X, the AV
DD
pin is no longer brought out to the package.
