Notes
13h
Internal Temperature
Hardware Trip Point
= 70°C
Can be written only if the write once bit in Configuration Register 2
has not been set. Values higher than 70°C will have no affect as the
fixed trip point in register 16h will be reached first.
14h
External Temperature
Hardware Trip Point
= 85°C
Can be written only if the write once bit in Configuration Register 2
has not been set. Values higher than 85°C will have no affect as the
fixed trip point in register 17h will be reached first.
15h
Test Register
0000 00X0
Setting Bit 0 of this register to 1 selects shutdown mode. Caution: Do
not write to any other bits in this register.
16h
Channel Mode Register
0000 0000
This register configures the input channels and configures VID0 to
VID4 as processor voltage ID or interrupt inputs.
17h
Internal Temperature
Fixed Hardware Trip Point
= 70°C
Read Only. Cannot be changed.
18h
External Temperature
Fixed Hardware Trip Point
= 85°C
Read Only. Cannot be changed.

Ext. Temp1 Value
Indeterminate
Read Only. Stores the measurement from a diode sensor connected
to Pins 13 and 14.
27h
Internal Temperature Value
Indeterminate
Read Only. This register is used to store eight bits of the internal
temperature reading.
28h
FAN1/AIN1 Value
Indeterminate
Read Only. Stores FAN1 or AIN1 reading, depending on the
configuration of Pin 5.
29h
FAN2/AIN1 Value
Indeterminate
Read Only. Stores FAN2 or AIN2 reading, depending on the
configuration of Pin 6.

2.5 V/Ext. Temp2 High Limit
Indeterminate
Stores high limit for 2.5 V input or, in temperature mode, this register
stores the high limit for a diode sensor connected to
Pins 17 and 18.
2Ch
2.5 V/Ext. Temp2 Low Limit
Indeterminate
Stores low limit for 2.5 V input or, in temperature mode, this register
stores the low limit for a diode sensor connected to
Pins 17 and 18.
