Platform Reset: The Intel
the platform (e.g., SIO, FWH, LAN, (G)MCH, TPM, etc.). The ICH8
asserts PLTRST# during power-up and when S/W initiates a hard reset
sequence through the Reset Control register (I/O Register CF9h). The
ICH8 drives PLTRST# inactive a minimum of 1 ms after both PWROK
and VRMPWRGD are driven high. The ICH8 drives PLTRST# active a
minimum of 1 ms when initiated through the Reset Control register (I/
O Register CF9h).
NOTE: PLTRST# is in the VccSus3_3 well.
Thermal Alarm: Active low signal generated by external hardware to
generate an SMI# or SCI.
Thermal Trip: When low, this signal indicates that a thermal trip from
the processor occurred, and the ICH8 will immediately transition to a
S5 state. The ICH8 will not wait for the processor stop grant cycle since
the processor has overheated.
S3 Sleep Control: SLP_S3# is for power plane control. This signal
shuts off power to all non-critical systems when in S3 (Suspend To
RAM), S4 (Suspend to Disk), or S5 (Soft Off) states.
Overcurrent Indicators: These signals set corresponding bits in
the USB controllers to indicate that an overcurrent condition has
occurred.
OC[7:1]# may optionally be used as GPIOs.
NOTE: OC[9:0]# are not 5 V tolerant.
USB Resistor Bias: Analog connection point for an external
resistor. Used to set transmit currents and internal load resistors.
USB Resistor Bias Complement: Analog connection point for an
external resistor. Used to set transmit currents and internal load
resistors.
