I/O
Note:
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 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. L2_TSTCLK may be tied to ground for normal machine operation, if extra 60x bus output hold is required on all 60x bus signals. See Table “60X Bus
Output AC Timing Specifications for the 7501,” on page 14, spec 15.
6. These pins are no connects on dd2.x and have no function. They will be added to dd3.x to select voltage levels for the L2 bus (A19) and the rest of the
I/O (W01). Leaving the pin unconnected will select the normal supply value. Connecting these pins to HRESET# or ground on dd3.x will select lower
voltage supply ranges.
