AN3097 The EVAL6460 controlled by the EVAL_IBU-STR7
Doc ID 16599 Rev 2 29/34
To start the conversion push the "Start0" or "Start1" buttons, in the text box you can read the
result register and the related voltage (the most significant bit of the result register is the
"done" flag).
3.2.11 How to use the digital comparator
The L6460 includes one digital comparator that can be used to signal, through the serial
interface, that a channel converted by the ADC is greater, greater-equal, lesser, lesser-
equal, or equal than a fixed value set by the serial interface or than the value converted by
the other ADC channel.
In the first software window click the L6460 device and then the "Digital compare" button,
the following window appears (Figure 34).
Figure 34. Digital comparator block diagram
In this window you can select the Data0 and Data1 source, to set the output update signal
and the comparison type. Finally you can enable or disable the comparison.
3.2.12 How to configure and program the device via the SPI sequencer
L6460 includes a sequencer tool able to configure the device registers and program some
command sequences.
In the first software window click the L6460 device and then the "SPI" button, in the SPI
window push the "Sequencer" button, the following window appears (Figure 35).
