Program Description
3.3.3 Measurement Section
The TSC2111 supports programmable, automatic temperature and auxiliary-input measurements. In the
auto measurement mode, the TSC2111 can auto start the TEMP1, TEMP2, AUX1, and/or AUX2
measurement after a programmable interval. The checkboxes and sliders 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
Enable External Bias Resistance box.
3.3.4 Threshold Section
The TSC2111 monitor the temperature and the auxiliary inputs and set corresponding flags if an input
exceeds the bounds set in the threshold registers.
In this section, if the threshold function has not been enabled ( Enable checkbox has not been checked),
the corresponding MAX/MIN slider does not move. Also note that the MAX value must be greater than or
equal to the MIN value.
3.3.5 Continuous Conversion Delay Section
In auto-measurement mode, the delays between the conversions are programmable. This section can be
used to program to delays between the continuous conversions.
The nontouch and touch auto measurement delays can be programmed individually. By clicking on the
corresponding Enable checkbox, the auto-measurement delay is enabled. The delay-time option allows
selection of delay-clock source and divider.
The clock used can be the internal oscillator or the external MCLK. The clock divider (CLKDIV) is used to
derive the 1-MHz clock for the programmable delay. This sets the CLKDIV so that MCLK/CLKDIV = 1
MHz.
3.3.6 Reinitialization and Reset
Two buttons on this screen allow the user to reset and reinitialize the TSC2111.
By clicking the SW Reset button, a software device reset is issued to the TSC2111. By clicking the Init
TSC2111 button, the control registers (for ADC and audio) revert back to the startup (firmware) default
settings.
To restore the TSC2111 EVM to its power-up state, click SW Reset, followed by Init TSC2111.
