Table 43. Register 1Eh, INT Temp Offset (Power-On Default 00h)
Bit
Name
R/W
7–0
Int Temp Offset
R/W
Description
This register contains the offset value for the internal temperature channel, a twos complement
result before it is stored or compared to limits. In this way, a sort of one-point calibration can be
done whereby the whole transfer function of the channel can be moved up or down. From a
software point of view, this may be a very simple method to vary the characteristics of the
measurement channel if the thermal characteristics change for any reason (for instance from one
chassis to another), if the measurement point is moved, if a plug-in card is inserted or removed, and
so on.

Description
1, if Ext1 value is above the high limit or below the low limit on the previous conversion cycle;
0 otherwise. This bit is set (once only) if a THERM mode is engaged as a result of Ext1 temp readings
exceeding the Ext1 THERM limit. This bit is also set (once only) if THERM mode is disengaged as a
result of Ext1 temperature readings going 5°C below Ext1 THERM limit.
1, if Ext 2 value (or A
IN9
if in voltage measurement mode) is above the /A
IN9
status = 0 high limit or
below the low limit on the previous conversion cycle; 0 otherwise. This bit is set (once only) if a
THERM mode is engaged as a result of Ext2 temperature readings exceeding the Ext2 THERM limit.
This bit is also set (once only) if THERM mode is disengaged as a result of Ext2 temperature readings
going 5°C below Ext2 THERM limit.
1, if 3.3 V STBY value is above the high limit or below the low limit on the previous conversion cycle;
0 otherwise.
1, if 3.3 V MAIN value is above the high limit or below the low limit on the previous conversion
cycle; 0 otherwise.
1, if +5 V value is above the high limit or below the low limit on the previous conversion cycle;
0 otherwise.
1, if V
CCP
value is above the high limit or below the low limit on the previous conversion cycle;
0 otherwise.
1, if +12 V value is above the high limit or below the low limit on the previous conversion cycle;
0 otherwise.
1, if
12 V value is above the high limit or below the low limit on the previous conversion cycle;
0 otherwise.
