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 one to this bit will lock in the values set into the ambient tempera-
ture automatic fan control register 13h. This register will not be able to be
written again until a reset is performed (either POR, Hard 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.

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
