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.
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.
Setting Bit 0 of this register to 1 selects shutdown mode. Caution: Do
not write to any other bits in this register.
This register configures the input channels and configures VID0 to
VID4 as processor voltage ID or interrupt inputs.

Read Only. Stores the measurement from a diode sensor connected
to Pins 13 and 14.
Read Only. This register is used to store eight bits of the internal
temperature reading.
Read Only. Stores FAN1 or AIN1 reading, depending on the
configuration of Pin 5.
Read Only. Stores FAN2 or AIN2 reading, depending on the
configuration of Pin 6.
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.
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.
