Electrical Characteristics
7.
VccRTC is the voltage applied to the VccRTC well of the ICH10. When the system is in a G3
state, this is generally supplied by the coin cell battery, but for S5 and greater, this is
generally VccSus3_3.

9.
CL_Vref = 0.27 (VccCL1_5). CL_VREF0 applies to all configurations.
Applies to Ultra DMA Modes greater than Ultra DMA Mode 4
10.
11.
12.
This is an AC Characteristic that represents transient values for these signals
Applies to Hogh-Speed USB 2.0.
3.3 V refers to VccSus3_3 for signals in the suspend well and to Vcc3_3 for signals in the
core well. See Table 3-2 or Table 3-3 for signal and power well association.
