NAME OF LOCATION FUNCTION

4 — R/W 0 MON2U

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.

3 — — 0 MON3U

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.

6 — — — TMPlo

This alarm flag goes high when the lower limit

of the temperature setting is violated.

5——— V

This alarm flag goes high when the upper limit

of the V

setting is violated.

4——— V

This alarm flag goes high when the lower limit

of the V

setting is violated.

3 — — — MON1hi

This alarm flag goes high when the upper limit

of the MON1 setting is violated.

2 — — — MON1lo

This alarm flag goes high when the lower limit

of the MON1 setting is violated.

1 — — — MON2hi
