3.5.3.3 Measurement Section
The TSC2101 supports programmable auto-temperature and auto-auxiliary
measurement mode. In the auto measurement mode, the TSC2101 can auto
start the TEMP1, TEMP2, AUX1, and/or AUX2 measurement after a
programmable interval. The checkboxes in the Measurement section provide
choices.
Additionally, the AUX1 and AUX2 can be configured to measure voltage or
resistance. Under the resistance measurement, the bias can be configured as
external or internal by checking or unchecking the box Enable External Bias
Resistance.
3.5.3.4 Threshold Section
Another feature with the temperature and auxiliary input measurements in
TSC2101 is that the maximum and minimum of the analog input can be set up
so that whenever the corresponding input signal goes outside the thresholds,
the corresponding flags are set.
