NOTES:
1. Negligible change when VccSus1_5 Internal VR is enabled. Internal VccSus1_5 VR is enabled through
ICH6-M strap option. This internal VR is tied to the Core well in S0. It is only tied to the VccSus3_3 rail for
sleep states.
2. Includes worst case leakage.
3. Vcc2_5 Internal VR enabled.
4. Vcc2_5 Internal VR disabled.
5. VccSus1_5 Internal VR enabled.
6. VccSus1_5 Internal VR disabled.
7. IccRTC data is taken with VccRTC at 3.0 V while the system is in G3 state at room temperature and only the
G3 state for this power well is shown to provide an estimate of battery life.
