I just have some questions for your AD7792/7793s.
Question-A: As for status register SR6(ERR) bit,
1)Do you have any explanations except for over range/under range of input?
eg. Fail Analo to Digital coversion though there is the input within the range.
2)When it is zero-calibration or full scale-calibration, can I set up this bit SR6?
If so, SR6=1, does this mean calibration fail, correct?
And should I do calibration many times before SR6=0(reset)?
Question-B:As for your offset register and full scale register,
1)I can write any data at first time. How can I deside the write-data? Do you have a good instruction? I would like to know the affecti for convertion data.
Question-C:As for not used pins,
1)I will not use REFIN(+)/AIN3(+), and REFIN(-)/AIN(-) pins. These pins will connect to GND, correct? Or put more than 0.1V?
