DESCRIPTION

Remote temperature reading of D2 when greater than the range flag.

0 = The local temperature is not greater than the range.

D2-High -ALR

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.

0 = The sensor is in a normal condition.

D1-FAIL-ALR

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.

0 = The sensor is in a normal condition.

D2-FAIL-ALR

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'.

Thermal alarm flag.

When the die temperature is equal to or greater than +150°C, the bit is set ('1') and the

THERM-ALR

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.
