BIT
NAME
DEFAULT R/W
DESCRIPTION
Remote temperature reading of D2 when greater than the range flag.
5 D2-High -ALR
0
0 = The local temperature is not greater than the range.
R _{1 = The local temperature is greater than the high-bound threshold.}
This bit is only checked when D2 is enabled (EN-D2 is '1'); this bit is ignored when EN-D2 is
'0'.
Remote sensor D1 failure flag.
4 D1-FAIL-ALR
0
0 = The sensor is in a normal condition.
R _{1 = The sensor is an open-circuit or short-circuit.}
This bit is only checked when D1 is enabled (EN-D1 is '1'); this bit is ignored when EN-D1 is
'0'.
Remote sensor D2 failure flag.
3 D2-FAIL-ALR
0
0 = The sensor is in a normal condition.
R _{1 = The sensor is an open-circuit or short-circuit.}
This bit is only checked when D2 is enabled (EN-D2 is '1'); this is ignored when EN-D2 is
'0'.
2 THERM-ALR
0
Thermal alarm flag.
When the die temperature is equal to or greater than +150°C, the bit is set ('1') and the
R THERM-ALR flag activates. The on-chip temperature sensor (LT) monitors the die
temperature. If LT is disabled, the THERM-ALR bit is always '0'. The hysteresis of this alarm
is 8°C.
