Program Description
3-20
In this section, if the threshold function has not been enabled, that is the Enable
checkbox has not been checked, the corresponding MAX/MIN slider does not
move. Also note that the MAX value must be larger or equal to the MIN value.
3.5.3.5 Continuous Conversion Delay Section
In the 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. Whenever the delay is enabled, by clicking on the corresponding
checkbox, the delay-time option shows up for the selection.
The clock used here can be the internal oscillator or the external MCLK. The
clock divider (CLKDIV) is used to get 1-MHz clock for the programmable delay.
This sets the CLKDIV so that MCLK/CLKDIV = 1 MHz.
3.5.3.6 Reinitialization and Reset
Two buttons on this screen allow the user to reset and reinitialize the TSC2101.
By clicking the button SW Reset
, a software device reset is issued to the
TSC2101. By clicking the button Init TSC2101 , the control registers (for ADC
and audio) revert back to the startup (firmware) default settings.
To bring the TSC2101 EVM back to its power-up status, you can click SW
Reset, followed by Init TSC2101 .
3.5.4 Audio Screens
Three tabs control the TSC2101 audio functions: Audio 1, Audio 2, and Audio
Effects Filters tabs.
Figure 3−10 shows the default condition of the Audio 1 tab with the following
sections:
INTERFACE:
set up the audio
I
2
S port
PLL: set up PLL parameters to get the desired FSref frequency
ADC: set up the audio ADC, and select the ADC input source
DAC/Outputs: set up the audio DAC and the all analog output features
GPIO1: set up GPIO1 function/status
GPIO2: set up GPIO2 function/status
