clearing AL bit in TMP112

This was not answered will close it now.
Alert can function as a comparator output or as an interrupt output. From the datasheet:
7.4.4 Thermostat Mode (TM)
The thermostat mode bit indicates to the device whether to operate in comparator mode (TM = 0 ) or interrupt
mode (TM = 1).
7.4.4.1 Comparator Mode (TM = 0)
In Comparator mode (TM = 0), the Alert pin is activated when the temperature equals or exceeds the value in the
T(HIGH) register and remains active until the temperature falls below the value in the T(LOW)register. For more
information on the comparator mode, see the High- and Low-Limit Register section.
7.4.4.2 Interrupt Mode (TM = 1)
In Interrupt mode (TM = 1), the Alert pin is activated when the temperature exceeds T(HIGH) or goes below T(LOW)
registers. The Alert pin is cleared when the host controller reads the temperature register. For more information
on the interrupt mode, see the High- and Low-Limit Register section.
