This bit goes high after a MON2 update has
occurred for the corresponding measurement
in bytes 66h to 67h. This bit can be written to
a 0 by the user and monitored to verify that a
conversion has occurred.
This bit goes high after a MON3 update has
occurred for the corresponding measurement
in bytes 68h to 69h. This bit can be written to
a 0 by the user and monitored to verify that a
conversion has occurred.
This alarm flag goes high when the upper limit
of the temperature setting is violated.
This alarm flag goes high when the lower limit
of the temperature setting is violated.
