2. These voltages are targets only. A variable voltage source should exist on systems in the event that a different voltage is required. See Section 2.3
and Table 2-1 for more information.
3. The voltage specification requirements are measured across VCC_SENSE and VSS_SENSE lands at the socket with a 100 MHz bandwidth oscillo-
scope, 1.5 pF maximum probe capacitance, and 1 MΩ minimum impedance. The maximum length of ground wire on the probe should be less than
5 mm. Ensure external noise from the system is not coupled into the oscilloscope probe.
4. Refer to Table 2-5 and Figure 2-2 for the minimum, typical, and maximum V
CC
allowed for a given current. The processor should not be subjected
to any V

combination wherein V
CC
exceeds V
