BIT
NAME
P R
FUNCTION
7 (MSB)
MASKALL
0
Masks all ALERT interrupts when high.
6
RUN/STOP
0
Standby mode control bit. If high, the device immediately stops converting and
enters standby mode. If low, the device converts.
5
MASK4*
0
Masks remote DX4 interrupts when high.
4
MASK3*
0
Masks remote DX3 interrupts when high.
3
MASK2
0
Masks remote DX2 interrupts when high.
2
MASK1
0
Masks remote DX1 interrupts when high.

NAME
FUNCTION
7 (MSB)
BUSY
A high indicates that the ADC is busy converting.
6
LHIGH
A high indicates that the local high-temperature alarm has activated.
5
LLOW
A high indicates that the local low-temperature alarm has activated.
4
OPEN
A high indicates one of the remote-diode continuity (open-circuit) faults.
3
ALARM
A high indicates one of the remote-diode channels has over/undertemperature alarm.
