Digital temperature sensor with overtemperature alarms
7.8.4 Status register (SR)
The contents of the status register reflect condition status resulting from all activities:
comparison between temperature measurements and temperature limits, the status of
A/D conversion, and the hardware condition of external diode to the device. Bit
assignments are listed in Table 9
. This register is read-only and its address is 02h. Upon
POR, all bits are set to zero.
Remark: Any one of the fault conditions, with the exceptions of Diode OPEN and
A/D BUSY, introduces an Alert interrupt (see Section 7.9.1.2
). Also, whenever a one-shot
command is executed, the status byte should be read after the conversion is completed,
which is about 38 ms (1 conversion time period) after the one-shot command is sent.
2
Local T_CRIT
mask.
The T_CRIT
output will be activated by a local temperature that exceeds
the local T_CRIT setpoint when this bit is LOW. The T_CRIT
output will not
be activated under this condition when this bit is HIGH.
0
1
Not defined; defaults to logic 0.
0
0
Fault queue.
A single remote temperature measurement outside the HIGH, LOW or
T_CRIT setpoints will trigger an outside limit condition resulting in setting
the status bits and associated output pins when this bit is LOW. Three
consecutive measurements outside of one of these setpoints are required
to trigger an outside of limit condition when this bit is HIGH.

RHIGH When logic 1, indicates a remote diode HIGH temperature alarm. POR state = 0.
3
RLOW When logic 1, indicates a remote diode LOW temperature alarm. POR state = 0.
2
OPEN When logic 1, indicates a remote diode disconnect. POR state = 0.
1
RCRIT When logic 1, indicates a remote diode critical temperature alarm. POR state = 0.
0
LCRIT When logic 1, indicates a local critical temperature alarm. POR state = 0.
