Notes:
1. OVdd supplies power to the processor bus, JTAG, and all control signals except the L2 cache controls (L2CE, L2WE, and
L2ZZ); L2OVDD supplies power to the L2 cache interface (L2ADDR[0-16], L2ASPARE, L2DATA[0-63], L2DP[0-7]
and L2SYNC-OUT) and the L2 control signals; and Vdd supplies power to the processor core and the PLL and DLL (after
ltering to become AVDD and L2AVDD respectively). These columns serve as a reference for the nominal voltage
supported on a given signal as selected by the BVSEL/L2VSEL pin congurations of Table 2 and the voltage supplied.
For actual recommended value of Vin or supply voltages see Table 3.
2. These are test signals for factory use only and must be pulled up to OVdd for normal machine operation.
