Temperature Monitor
Temperature Value
This tab displays the temperature reading from the selected
device as well as the status of the alarms. This tab includes five
control options (see Figure 8):
This displays the actual ADC temperature in twos complement
and degrees Celsius respectively.

Log Data
This section allows you to update the high, low, critical, and
hysteresis limits. These ADC values are loaded into the device.
Because the conversion format is twos complement, any value
over 4095 is a negative number. To change the value, you can
use the arrow keys or type a number in the box to update the
limits. The graph labeled Temperature Conversion Measurement
displays the variation in time of the high and low temperature
limits as well as the current temperature in twos complement
format. At startup, the evaluation software initializes the tempera-
ture limits registers (THIGH, TLOW, TCRIT, and THYST) to the default
values shown in Figure 6.
Temperature Values
Temperature Threshold
If the temperature goes above or below the high and low limits
defined in the Set Temperature Limits section or above the
critical threshold, the Temperature High Limit Threshold,
Temperature Low Limit Threshold, and Temperature Critical
Threshold indicators appear green.
