Electrical Specifications
The processor uses the VID_VCCCACHE value to support automatic selection of the
power supply voltages. Table 2-38 specifies the voltage level corresponding to the state
of VID_VCCCACHE. A ‘1’ in this table refers to a high voltage level and a ‘0’ refers to a
low voltage level. See the Ararat I Regulator Module Design Guide for more details.
2.9 RSVD, Unused, and DEBUG Pins
All RSVD (RESERVED) pins must be left unconnected. Connection of these pins to
power, VSS, or to any other signal (including each other) can result in component
malfunction or incompatibility with future processors.
