Setting this bit masks the thermal interrupts for the INT output ONLY. The THERM
output will still be generated, regardless of the setting of this bit.
Writing a 1 to this bit will lock in the values set into the ambient temperature
automatic fan control register 13h. This register will not be able to be written again
until a reset is performed (either POR, Hard Reset, or Soft Reset).
Writing a 1 to this bit will lock in the values set into the remote temperature automatic
fan control register 14h. This register will not be able to be written again until a reset
is performed (either POR, Hard Reset, or Soft Reset).
If this bit is 0, the THERM output operates in default mode.
If this bit is 1, the THERM output operates in ACPI mode.
Reserved
Setting this bit to 1 enables Pin 21 as an active high interrupt input, provided Pins 20
to 24 have been configured as interrupts by setting Bit 7 of the Channel Mode
Register. Power−on default = 0.
Setting this bit to 1 enables Pin 20 as an active high interrupt input, provided Pins 20
to 24 have been configured as interrupts by setting Bit 7 of the Channel Mode
Register. Power−on default = 0.
