1
1.2V power supply for SATA interface. Analog transmitter power.
3
1.30V or 1.00V CPU power supply for IA-32 core. This supply is 1.30V for
1200MHz, 1.30V for 1066MHz, and 1.00V for 600MHz (see V_SEL signal
1
description in the ICH Miscellaneous signals).
2.5V power supply for Gigabit Ethernet interfaces.
4
2.5V sustain power supply for Gigabit Ethernet interfaces.
4
3.3V power supply for the RTC (this supply can drop to 2.0V if all other planes are
shut off). This power is not expected to be shut off unless the RTC battery is
removed or drained.mthellomthelloNote: Implementations must not attempt to 1
clear CMOS by using a jumper to pull VCCPRTC low. Clearing CMOS can be done
by using a jumper on RTEST_N or GPI.
3.3V sustain supply for IO logic
