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.
This register contains the measured value of the internal temperature channel.
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
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.
