A 1 disables the corresponding interrupt status bit, preventing it from causing the
interrupt output. The status bit is not affected. Default = 1.
A 1 disables the corresponding interrupt status bit, preventing it from causing the
interrupt output. The status bit is not affected. Default = 0.
A 1 disables the corresponding interrupt status bit, preventing it from causing the
interrupt output. The status bit is not affected. Default = 0. This bit has no effect in
ALERT comparator mode, because the corresponding status bit does not generate an
ALERT in that mode.

When the local temperature exceeds this temperature, the corresponding interrupt
status bit is set.
When the local temperature falls below this temperature, the corresponding interrupt
status bit is set.
When the local temperature exceeds this temperature, the corresponding status bit is
set and the THERM output is activated.
When the Remote 1 temperature exceeds this temperature, the corresponding interrupt
status bit is set.
When the Remote 1 temperature falls below this temperature, the corresponding
interrupt status bit is set.
