NOTES:
1. 1.8V and 3.3V LAN Icc(max) in S0 was measured running Full Duplex LAN test.
2. 1.8V SUS Icc(max) in S0 state was measured while running a test that continuously accessed PM registers.
3. 3.3V SUS Icc(max) in S0 state was measured running a concurrency test, in which all 4 USB ports were
exercised.
4. 1.8V Core and 3.3V I/O Icc(max) in S0 state was measured running a test that generated a constant stream
of CPU->PCI writes, with an inverting pattern, causing data lines to switch on every clock.
