NOTES:
1. HIREF and HI_VSWING are derived from 1.5 V which is the nominal core voltage for the ICH5. Voltage
2. Includes CLK14, CLK48, CLK66, LAN_CLK and PCICLK
3. Nominal value of HIREF is 0.350 V. The spec is at nominal Vcc1_5. Note that HIREF will vary linearly with
4. Nominal value of HIVSWING is 0.800 V. The spec is at nominal Vcc1_5. Note that HIVSWING will vary
