Notes
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 VID 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 con-
nected 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 con-
nected to Pins 17 and 18.
