The “n” as the first letter of a signal name or the “#” as the suffix of a signal name indicates an “Active Low”
signal.
VCC and VSS pins are for Super I/O Blocks. HVCC and HVSS are dedicated for the Hardware Monitoring
Block.
VTR can be connected to VCC if no wakeup functionality is required.
If the 32kHz input clock is not used the CLKI32 pin must be grounded. There is a bit in the configuration
register at 0xF0 in Logical Device A that indicates whether or not the 32KHz clock is connected. This bit
determines the clock source for the fan tachometer, LED and “wake on specific key” logic. Set this bit to ‘1’
if the clock is not connected.

NAME
+3.3V VCC pin dedicated to the Hardware
Monitoring block.
+3.3V Standby power if monitoring in low
power states is required.
Analog Ground. Internally connected to all
of the Hardware Monitoring Block circuitry.
System Management Bus bi-directional
Data. Open Drain output.
System Management Bus Clock.
The lowest order programmable bit of the
SMBus Address Input.
Minimum 20msec low Reset output pulse
Interrupt output for temperature and voltage
interrupts.

Defaults
Optionally, can be configured to read the
VID4 Digital Input, a voltage supply readout
from the processor. This value is read in the
VID4 Register.
Analog input for +5V
Analog input for +3.3V
Analog input for +2.5V
Analog input for +Vccp (processor voltage:
0 to 3.0V).
Analog input for +1.8V
Analog Input for +1.5V
This is the negative Analog input (current
sink) from the remote thermal diode. This
serves as the negative input into the A/D.
Digital Input.
initiates XNOR chain test mode.
This is the positive input (current source)
from the remote thermal diode. This serves
as the positive input into the A/D.
See D0+ description.
