FUNCTION
6—
R/W
0VCCU
This bit goes high after a VCC update has
occurred for the corresponding measurement
in bytes 62h to 63h. This bit can be written to
a 0 by the user and monitored to verify that a
conversion has occurred.
5—
R/W
0
MON1U
This bit goes high after a MON1 update has
occurred for the corresponding measurement
in bytes 64h to 65h. This bit can be written to
a 0 by the user and monitored to verify that a
conversion has occurred.
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.
