See Table 1.
Resistor status bit. A high indicates that both
resistors are in high-impedance mode. A low
indicates that both resistors are operating
normally.
Resistor control bit. Setting this bit high
causes both resistors to go into a high-
impedance state.
This status bit is high when OUT1 is high,
assuming there is an external pullup resistor
on OUT1.
This status bit is high when OUT2 is high,
assuming there is an external pullup resistor
on OUT2.
This status bit goes high when V
below the POA level.
This bit goes high after a temperature and
address update has occurred for the
corresponding measurement in bytes 60h to
61h. 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 V
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.
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.
